WebDec 20, 2024 · The cosecant function is therefore odd. Finally, the secant function is the reciprocal of the cosine function, and the secant of a negative angle is interpreted as sec( − θ) = 1 cos( − θ) = 1 cosθ = secθ. The secant function is therefore even. To sum up, only two of the trigonometric functions, cosine and secant, are even. WebOct 6, 2024 · An odd function is one in which f( − x) = − f(x).

WebApr 7, 2024 · The Cos Theta Formula is a Mathematical formula used to calculate the Cosine of an angle. It can be abbreviated as Cos (θ) and looks like this: Cos (θ) = adjacent/hypotenuse. In other words, it takes the length of the adjacent side (the side next to the angle) and divides it by the length of the hypotenuse (the longest side of a right triangle). WebAug 2, 2006 · Try graphing it, that should help. Sin (x) is odd because sin (-x)=-sin (x), whereas cos (x) is even because cos (-x)=cos (x). When looking at the definitions of sin and cos on the unit circle it should be obvious... if you go backwards x radians instead of forwards, you end up on the opposite side of the x-axis, but the same side of the y-axis.
