prove cot(θ)=(sin(θ))/(cos(θ))

prove

cot (θ) = \frac{sin ( θ )}{cos ( θ )}

False

Solution steps

cot (θ) = \frac{sin ( θ )}{cos ( θ )}

Show that the two sides are not equal

\Rightarrow False

(1 - tan^{2} (θ))^{2} = sec^{2} (θ) - 4 tan^{2} (θ)

- cos^{2} (x) + sin^{2} (x) = 1 - 2 cos^{2} (x)

4 sin (2 x) = 8 sin (x) cos (x)

cos (\frac{π}{2} - x) csc (x) = 1

csc (x) - sec (x) sin^{2} (x) = cos (x)
