Sin π 2 −α =cosα cos π 2 −α =sinα We have already proven all these identities, except the cofunction identities We have already mentioned them when we studied transformations of the graphs of sine and cosine There is a nice way to prove them using a triangle Consider the triangle below In this triangle, we have sinα = a c cosβThe sin value when angle of a right triangle equals to 90 ° is called sine of angle 90 degrees In mathematics, it is written as sin ( 90 °) according to sexagesimal system sin ( 90 °) = 1 The value of sin of 90 degrees is 1 exactly and it is often called as trigonometric function (or ratio) for standard angle generally The direction #theta= (3pi)/2 separates 3rd and 4th quadrants Sine is negative in these quadrants sin(π θ) = sin(2π− θ) = − sinθ sin(3π 2) =

If the angle is multiple of π/2, ie π/2, 3π/2, 5π/2, then sin becomes cos cos becomes sin If the angle is multiple of π, ie π, 2π, 3π, then sin remains sin cos remains sin 2The sign depends on the quadrant angle is in sin (π/2 – x) Since it is π/2, sin will become cos Here x is an acute angle So, π/2 – x = 90 – x is anTrigonometric identities are equations involving the trigonometric functions that are true for every value of the variables involved Some like the following sin 2 ( x ) cos 2 ( x ) = 1 1 tan 2 ( π 2 − x ) = sec ( x )Sin 90° = 1 The most common trigonometric sine functions are Sin 90 degree plus theta Sin 90 degree minus theta Some other trigonometric sine identities are as follows Sin 2x = 2 sin x cos x In the same way, we can derive other values of sin angles like 0°,
