Question

prove that (sin 2theta +1)/cos2theta =(cos theta +sin theta)/(cos theta -sin theta)

Answer 1

is that \[\sin(2\theta)\]or\[\sin^2\theta\]?

Answer 2

sin(2θ)

Answer 3

Multiply the numerator and denominator of the right hand side by \( (\cos \theta + \sin \theta )\) and the result should follow instantly.

Answer 4

alright lemme try

Answer 5

\[[( \sin 2\theta +1)/ \cos2\theta ] \times(\cos \theta +\sin \theta)\]

Answer 6

is this what you asked me to do?

Answer 7

no that's the left-hand side
do the other side instead

Answer 8

OHH I SEEE

Answer 9

i got the answer hurray!
