Cos π/2 value 303273

Plot of the six trigonometric functions, the unit circle, and a line for the angle = radians The points labelled 1, Sec(θ), Csc(θ) represent the length of the line segment from the origin to that point Sin(θ), Tan(θ), and 1 are the heights to the line starting from the axis, while Cos(θ), 1, and Cot(θ) are lengths along the axis starting from the originTrigonometric Identities Trigonometric identities are equations involving the trigonometric functions that are true for every value of the variables involved Some of the most commonly used trigonometric identities are derived from the Pythagorean Theorem , like the following sin 2 ( x) cos 2 ( x) = 1 1 tan 2 ( x) = sec 2 ( x)Find m if the following equation holds true 1 tan 2 θ 1 cot 2 θ = ( 1 tan θ 1 cot θ ) m Medium View solution >
