prove 1/(sin^2(θ))=1-tan^2(θ)

prove

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

False

Solution steps

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

Show that the two sides are not equal

For

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

plug in

θ = 1

\frac{1}{sin ^{2} ( 1 )} = 1.41228 \dots

\frac{1}{sin ^{2} ( 1 )}

Refine to a decimal form

= 1.41228 \dots

1 - tan^{2} (1) = - 1.42551 \dots

1 - tan^{2} (1)

Refine to a decimal form

= - 1.42551 \dots

The two sides are not equal

\Rightarrow False
