The TCU Horned Frogs men's basketball team represents Texas Christian University, located in Fort Worth, Texas, in NCAA Division I men's basketball competition. Since 2016, the Horned Frogs have been led by TCU Lettermen's Hall of Fame member, head coach Jamie Dixon. TCU has competed in the Big 12 Conference since 2012, competed in the Mountain West Conference, Conference USA, Western Athletic Conference and Southwest Conference; the Horned Frogs play their home games on campus at Ed & Rae Schollmaier Arena known as Daniel–Meyer Coliseum, which reopened in December 2015 after a $72 million renovation. The Horned Frogs began varsity intercollegiate competition in men's basketball in 1908, when the university was located in Waco, Texas. In their first recorded game, the Frogs faced then-cross-town rival Baylor in a 6–37 loss. TCU moved its campus from Waco to Fort Worth, after a fire destroyed the central Texas' school's main building in 1910. TCU competed as an independent and as part of the Texas Intercollegiate Athletic Association until joining Southwest Conference competition for the 1923–24 season, where the Frogs won their first-ever SWC game in a January 9, 1924, game at Rice University.

During the early, independent and TIAA years, TCU was led by at least six different coaches from 1908 through 1923, played five or fewer games or did not field teams in 7 of those 15 seasons. The Horned Frogs were led into the Southwest Conference in 1923 by a new basketball and football coach, Fort Worth native Matty Bell. Bell transformed the program, accruing a 71–41 record over his six seasons at TCU and leading the Horned Frogs to second and fourth place finishes during his tenure. Bell was succeeded by Francis Schmidt, who left the Arkansas Razorbacks to coach TCU basketball and football. On the gridiron, Schmidt led the Frogs to their first SWC title and the gridiron in 1932, on the hardwood, Schmidt led the Frogs to a combined 72–24 record over five seasons and Southwest Conference championships in 1931 and 1934; the 1931 SWC championship was the Frogs' first league title in men's basketball. Schmidt departed Fort Worth after five seasons to become the head football coach at Ohio State.

Coach Schmidt's departure after the 1934 SWC championship season was followed by a 16-year drought for TCU basketball. TCU football coach Dutch Meyer fared far better leading the Frogs' football team, where he claimed two national championships, in 1935 and 1938, three SWC football titles over his 19-year football-coaching tenure, than he did in his three seasons at the helm of TCU basketball. Meyer's basketball record from 1934 through 1937 totaled on 10–37. Meyer was replaced by former TCU basketball and football player Mike Brumbelow, who had two SWC wins over the following four seasons, with an overall record of 22–64. Brumbelow was replaced by Hub McQuillan, who led the Frogs to middle-of-the-league finishes in the first 5 of his 7 years as head coach of TCU basketball. Buster Brannon, a former TCU player under Francis Scmidt, led Horned Frogs basketball for nearly two decades, from 1948 through 1967. Brannon amassed a 205–259 record over 19 seasons and led the Frogs to four Southwest Conference championships in 1951, 1952, 1953 and 1959, the program's first three NCAA Tournament appearances in 1952, 1953 and 1959.

Brannon's recorded faded in the 1960s, when the Frogs finished near the bottom of the league every year until Brannon's retirement from coaching in 1967. The Brannon era saw the opening of Daniel–Meyer Coliseum in 1961. Johnny Swaim, a former player for Brannon, coached the Frogs from 1967 through 1977. Swaim led the Frogs to Southwest Conference titles and the NCAA Tournament in 1967, his first season at the helm, in 1971; the Frogs' 1967 NCAA Tournament appearance saw the Frogs' first-ever Tournament win and the program's only appearance in what is now known as the Elite Eight. Swaim abruptly retired from coaching after the 1977 season, remaining in Fort Worth as a businessman until his death in 1995. After Swaim's retirement, Tim Somerville led the Frogs for the following two seasons, notching only a 10–43 record. On March 21, 2016, TCU hired Pitt head coach and former Horned Frogs' letterman Jamie Dixon as the Frogs' next head basketball coach. Prior to his return to Fort Worth as the 22nd head coach of TCU basketball, Dixon spent 13 years as the head coach at Pitt, won four national coach of the year awards, ranked as the 9th winningest, active Division I head coach.

Dixon's impact at TCU was immediate, where in his first season he landed Jaylen Fisher, the highest-rated recruit in TCU history, led the Frogs to their best conference record and finish, best overall record, first postseason tournament since joining the Big 12 in 2012, knocked off the No. 1 ranked Kansas Jayhawks in the 2017 Big 12 Tournament in Kansas City–marking the program's first-ever win over a #1 ranked team. The Horned Frogs won the 2017 NIT Championship on March 30, to cap off Dixon's first season with a 24–15 record; the Horned Frogs qualified as an at-large bid for the 2018 NCAA Division I Men's Basketball Tournament, snapping a 20-year drought. Legend: = Conference Regular Season Champion = Conference Tournament Champion = Conference Division Champion The Horned Frogs have appeared in eight NCAA Tournaments, their combined record is 5–8. The Horned Frogs have appeared in eight National Invitation Tournaments, their combined record is 17–7. They were NIT champions in 2017; the Horned Frogs have appeared in one College Basketball Invitational.

Their record is 1–1

Driven is a motoring television programme launched by Channel 4 in 1998 as a rival to the successful and long-running BBC series Top Gear. The style was similar to its rival, but with additional features such as the "Driven 100", a road test of three cars in the same class, where each car would be given marks for qualities such as practicality and cost of ownership; the car with the highest total score would be the winner. The programme launched with the concept that the presenters should interact with each other rather than present items on their own, as was the case on Top Gear; the first series featured a "headquarters", a racing team truck, set on a former USAF base at which cars were put through their paces. These concepts resurfaced in the reborn Top Gear soon after. Presented by Mike Brewer, James May and Jason Barlow, subsequent series featured the rally driver Penny Mallory and the racing driver Jason Plato. During the show's run, both May and Barlow left the show to join the old format of BBC's Top Gear.

Following the creation of Fifth Gear and the revival of Top Gear, Driven was cancelled by Channel 4 in 2002. Plato went on to present Fifth Gear, May joined the newly relaunched Top Gear, Brewer presented ITV's Pulling Power and Mallory could be seen on ITV4's Used Car Roadshow.

The sunrise equation as follows can be used to derive the time of sunrise and sunset for any solar declination and latitude in terms of local solar time when sunrise and sunset occur: cos ⁡ ω ∘ = − tan ⁡ ϕ × tan ⁡ δ where: ω ∘ is the hour angle at either sunrise or sunset. The Earth rotates at an angular velocity of 15°/hour. Therefore, the expression ω ∘ × 15 ∘ h o u r gives the interval of time before and after local solar noon that sunrise or sunset will occur; the sign convention is that the observer latitude ϕ is 0 at the equator, positive for the Northern Hemisphere and negative for the Southern Hemisphere, the solar declination δ is 0 at the vernal and autumnal equinoxes when the sun is above the equator, positive during the Northern Hemisphere summer and negative during the Northern Hemisphere winter. The expression above is always applicable for latitudes between the Arctic Circle and Antarctic Circle. North of the Arctic Circle or south of the Antarctic Circle, there is at least one day of the year with no sunrise or sunset.

Formally, there is a sunrise or sunset when − 90 ∘ + δ < ϕ < 90 ∘ − δ during the Northern Hemisphere summer, when − 90 ∘ − δ < ϕ < 90 ∘ + δ during the Northern Hemisphere winter. Out of these latitudes, it is either 24-hour 24-hour nighttime. Note that the equation above neglects the influence of atmospheric refraction and the non-zero angle subtended by the solar disc; the times of the rising and the setting of the upper solar limb as given in astronomical almanacs correct for this by using the more general equation cos ⁡ ω ∘ = sin ⁡ a − sin ⁡ ϕ × sin ⁡ δ cos ⁡ ϕ × cos ⁡ δ with the altitude of the center of the solar disc set to about −0.83°. The generalized equation relies on a number of other variables which need to be calculated before it can itself be calculated; these equations have the solar-earth constants substituted with angular constants expressed in degrees. N = J d a t e − 2451545.0 + 0.0008 where: n is the number of days since Jan 1st, 2000 12:00. J d a t e is the Julian date. 0.0008 is the fractional Julian Day for terrestrial time.

TT was set to 32.184 sec lagging TAI on 1 January 1958. By 1972, when the leap year was introduced, 10 sec were added. By 1 January 2017, 27 more seconds were added coming to a total of 69.184 sec. 0.0008=69.184 / 86400 without DUT1. J ⋆ = n − l w 360 ∘ where: J ⋆ is an approximation of mean solar time at n expressed as a Julian day with the day fraction. L ω is the longitude west of the observer on the Earth. C = 1.9148 sin ⁡ + 0.0200 sin ⁡ + 0.0003 sin ⁡ where: C is the Equation of the center value needed to calculate lambda. 1.9148 is the coefficient of the Equation of the Center for the planet the observer is on λ = mod 3 60 {\displays

Calculations in the Newman–Penrose formalism of general relativity begin with the construction of a complex null tetrad, where is a pair of real null vectors and is a pair of complex null vectors. These tetrad vectors respect the following normalization and metric conditions assuming the spacetime signature: l a l a = n a n a = m a m a = m ¯ a m ¯ a = 0. Only after the tetrad gets constructed can one move forward to compute the directional derivatives, spin coefficients, Weyl-NP scalars Ψ i, Ricci-NP scalars Φ i j and Maxwell-NP scalars ϕ i and other quantities in NP formalism. There are three most used methods to construct a complex null tetrad: All four tetrad vectors are nonholonomic combinations of orthonormal holonomic tetrads. In the context below, it will be shown. Note: In addition to the convention employed in this article, the other one in use is; the primary method to construct a complex null tetrad is via combinations of orthonormal bases. For a spacetime g a b with an orthonormal tetrad, g a b = − ω 0 ω 0 + ω
