prove csc^2(θ)(1-cos^2(θ))=cos(pi/2)

prove

csc^{2} (θ) (1 - cos^{2} (θ)) = cos (\frac{π}{2})

False

Solution steps

csc^{2} (θ) (1 - cos^{2} (θ)) = cos (\frac{π}{2})

Show that the two sides are not equal

\Rightarrow False

tan (x) + cot (2 x) = sec (2 x)

csc (θ) (csc (θ) - sin (θ)) = cot^{2} (θ)

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

cos^{2} (x) = cos (x) cos (x)

tan^{2} (x + c) + 1 - (tan (x + c))^{2} = 1
