This? \[\large \sin^2\theta+\cos^2\theta=1\]
yes
Well, let's see... How to break this to you... cosθ can literally be any value from [-1 , 1] Let me explain... the value of cosθ depends on the value of θ, right?

Well, unfortunately (fortunately?) ANY value of θ would make this statement true sin²θ + cos²θ = 1
he/she needs to solve for cos so, subtract sin^2 term from both sides, what u get ?
Oops... Must have been overexcited :) My bad
Im trying to write it but its giving me a hard time
±√(1 + sin2Θ)
did you mean \(\pm \sqrt{1-\sin^2 \theta}\) ??
yes I pasted the wrong one Sorry, my computer is acting really crazy today
ohh..if you meant that, then you are correct.
ok thanks you made this very easy, thank you.. :)
glad to hear :) welcome ^_^
