prove sec^2(θ)= 1/(cos^2(θ))

prove

sec^{2} (θ) = \frac{1}{cos ^{2} ( θ )}

True

Solution steps

sec^{2} (θ) = \frac{1}{cos ^{2} ( θ )}

Manipulating left side

sec^{2} (θ)

Express with sin, cos

= \frac{1}{cos ^{2} ( θ )}

We showed that the two sides could take the same form

\Rightarrow True

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

sin (x) = \frac{1}{2}

\frac{2 sin ( x ) cos ( x )}{2 sin ^{2} ( x )} = cot (x)

cos^{2} (\frac{x}{2}) = \frac{sec ( x ) + 1}{2 sec ( x )}

1 + tan^{2} (y) = sec^{2} (y)
