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

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
