Question

The question is :-
$\sin(\pi - x ) = \sin(x)$
Answer is in the attachment...
Is it correct???
If yes, then plzzz explain how!?????

Answer 1

Yes it is,
$sin(\pi - x) = sinx$

you can prove it by using

sin (a - b) = sina cosb - cosa sinb

$sin(\pi - x) = sin\pi \: cosx - cos\pi \: sinx$

0 × cosx - (-1) × sinx

0 + sinx = sinx

Hence proved
