prove cos(t)cot(t)=(1-sin^2(t))/(sin(t))

prove

cos (t) cot (t) = \frac{1 - sin ^{2} ( t )}{sin ( t )}

True

Solution steps

cos (t) cot (t) = \frac{1 - sin ^{2} ( t )}{sin ( t )}

Manipulating left side

cos (t) cot (t)

Express with sin, cos

= \frac{cos ^{2} ( t )}{sin ( t )}

Rewrite using trig identities

= \frac{1 - sin ^{2} ( t )}{sin ( t )}

We showed that the two sides could take the same form

\Rightarrow True

csc (2 x) = \frac{1 + cot ^{2} ( x )}{2 cot ( x )}

(1 - cos (θ)) (1 + cos (θ)) (1 + cot^{2} (θ)) = 1

tan^{2} (θ) - sin^{2} (θ) = sin^{2} (θ) tan^{2} (θ)

cos^{2} (2 u) - sin^{2} (2 u) = cos (4 u)

tan (u) cot (u) - cos^{2} (u) = sin^{2} (u)
