how do I find \(tan^2\theta\)
\(sin^2\theta \)\(cos^2\theta \)
Are you dividing these, brkr19 ???
no, I was wondering how to solve each of the three, sorry for the confusing spacing, old laptop has troubles XD.
how would you find
sin^2(x)
because you can't just square the answer, and I forgot the proof
There's nothing to "solve"....we can just express each one in numerous ways......for instance....
tan^2θ = sin^2θ/cos^2θ = sec^θ - 1 = 1 / cot^2θ .....etc.
Similarly
sin^2θ cos^2θ = (1/4) [sin(2θ)]^2 = sin^2θ [ 1 - sin^2θ] = sin^2θ - sin^4θ .....etc.
