Use this property \[\sin^2(\theta)+\cos^2(\theta)=1\] to find \(cos(\theta)\) Then use \[\tan(\theta)=\frac{ \sin(\theta) }{ \cos(\theta) }\] to find the tan.

OpenStudy (maemae16):

I'm confused where did the \[\sin ^2 and \cos ^2 \] come from

OpenStudy (math&ing001):

That's the Pythagorean identity https://en.wikipedia.org/wiki/Pythagorean_trigonometric_identity You can always use it.
