Prove the identity sin4x=2sin2xcos2x
Musya8 [376]
There is a trig identity called the sum of 2 angles for sin its<span>
sin(a+b)=sin(a)cos(b)+cos(a)(sin(b)
</span>
You will need to use it. So in your question split the 4x in 2 equal parts 2x and 2x
 <span>
</span><span>sin(4x)=sin(2x+2x)

</span>Now using the expansion above you will get

<span>sin(2x+2x)=sin(2x)×cos(2x)+cos(2x)×sin(2x)

</span>And it will simplify to 

<span><span>2sin(2x)cos(2x)

I hope this helps you! Good luck :)</span></span>
