WebRight-Angled Triangle. The triangle of most interest is the right-angled triangle. The right angle is shown by the little box in the corner: Another angle is often labeled θ, and the three sides are then called: Adjacent: adjacent (next to) the angle θ; Opposite: opposite the angle θ; and the longest side is the Hypotenuse WebThe cot/csc Triangle The cot q and csc q are defined by a triangle whose height is one and whose hypotenuse is on the terminal side of the angle. The sin/cos, tan/sec, and cot/csc Triangles All three of the triangles used to define the trigonometric functions are shown in figure below.

WebJan 18, 2024 · Cosecant is notated or abbreviated by CSC since it is the reciprocal of the sine of an angle. There are six basic trigonometric functions in any right-angle triangle where sinθ,cosθ, s i n θ,... WebSecant (sec) - Trigonometry function. (See also Secant of a circle ). In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just 'sec'. Of the six possible trigonometric functions, secant, cotangent, and cosecant, are rarely used. grand isle louisiana fishing map
