#####

\[\cos^2 x + \sin^2 x = 1\]

What do you get if you divide both sides by $\cos^2 x$??

\[1 + \tan^2 x = \sec^2 x\]

#####

\[\sin^2 x + \cos^2 x = 1\]

What do you get if you divide both sides by $\sin^2 x$??

\[1 + \cot^2 x = \csc^2 x\]

\(\cos^2 x + \sin^2 x = 1\) What do you get if you divide both sides by $\cos^2 x$?

\[1 + \tan^2 x = \sec^2 x\]

\(\sin^2 x + \cos^2 x = 1\) What do you get if you divide both sides by $\sin^2 x$?

\[1 + \cot^2 x = \csc^2 x\]
