Question

verify the identity: cos theta/1-sin theta = 1+sin theta/cos theta

Answer 1

well solve the one on the left replace cos theta with (1-sin theta) and 1- sin theta to cos theta.

Answer 2

oh no!

Answer 3

that gives you the same identity to the right

Answer 4

oh it should be 1+ sin theta

Answer 5

hahahahahahahaha

Answer 6

yeah except that \(\cos(\theta)\neq 1+\sin(\theta)\)

Answer 7

\[\cos^2(\theta)=1-\sin^2(\theta)\\
\cos^2(\theta)=(1+\sin(\theta))(1-\sin(\theta))\] go from there

Answer 8

thank you very much :)
