Answer 2

Different calues of sine and cosine function for angles which are multiples of π/2 and π.​

Step 1: Values of sine.

$Sin 0^o = 0$

$sin\frac{\pi }{2} = 1$

$sin\pi = 0$

$sin\frac{3\pi }{2} = -1$

$sin 2\pi = 0$

Step 2: Values of cosines.

$Cos 0^o =1$

$cos\frac{\pi }{2} = 0$

$cos\pi = -1$

$cos\frac{3\pi }{2} = 0$

$cos 2\pi = 1$
