Question

Write the trigonometric expression in terms of sine and cosine, and then simplify.

tan(theta) // sec(theta) - cos(theta)

Answer 1

tan = sin/cos
sec = 1/cos

Answer 2

nite lol...and you too star :) librarys closing up on me...

Answer 3

Are you literally in a library?

Answer 4

Thanks a lot amistre :)

Answer 5

You can plug in the given suzi has given you and you'll get the following:\[\tan \theta /(\sec \theta - \cos \theta) = (\sin \theta/\cos \theta)/[(1-\cos^2 \theta)/\cos \theta]\]
now simplify :
\[= (\cos \theta \sin \theta)/(\cos \theta \sin^2 \theta)\]

\[= 1/\sin \theta\]
