Now we are cooking
working on the left
1/cos t - cos t
1/cos t -cos^2 t/cos t
(1 - cos^2 t)/cos t
sin^2 t/cos t
(sin t/cos t) sin t
tan t sin t
which is on the right
Column 1 Column 2
sec theta - cos theta
tan theta sin theta
Question: how do you get column 1 to be the same as column 2 ?? using the eight fundamental identities
