Question

loser66 · Answer

break tan = sin/cos
          sec = 1/ cos
make them have the same denominator and you can get the right hand side

I am still confused.  How do I make the left and right side match?

loser66 · Answer

i gave you the way, just apply.

anonymous · Answer

Ok, so now I have
-(sin x/cos x)^2+(1/cos x)^2=1 
correct?

loser66 · Answer

you don't have 1 from the right hand side, you are trying to get it. Therefore, you cannot write it down, Take it off

anonymous · Answer

I was just carrying the right hand side down.  I know it does not equal it yet.  I believe I need to use the Pythagorean Identity sin^2x+cos^2x=1 now, but I am not sure what to do with it.
