is that \[\sin(2\theta)\]or\[\sin^2\theta\]?
sin(2θ)
Multiply the numerator and denominator of the right hand side by \( (\cos \theta + \sin \theta )\) and the result should follow instantly.

alright lemme try
\[[( \sin 2\theta +1)/ \cos2\theta ] \times(\cos \theta +\sin \theta)\]
is this what you asked me to do?
no that's the left-hand side do the other side instead
OHH I SEEE
i got the answer hurray!
i have another question i need help with
prove that \[\cos 4x =8\cos ^{4}x - 8\cos ^{2}x +1\]
