Question

show that sin(π\2+thita)= cos thita​

Answer 1

Answer :

$\to \sin( \frac{\pi}{2} + \theta) = \cos( \theta)$

Explaination :

$\to \sin( \frac{\pi}{2} + \theta) \\ \\ \to \sin( \frac{\pi}{2}) \cos( \theta) + \sin( \theta) \cos( \frac{\pi}{2} ) \\ \\ \to 1 \times \cos( \theta) + \sin( \theta) \times 0 \\ \\ \to \cos( \theta)$
