prove (cos(θ))^2=cos^2(θ)

prove

(cos (θ))^{2} = cos^{2} (θ)

True

Solution steps

(cos (θ))^{2} = cos^{2} (θ)

The two sides are the same

\Rightarrow True

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

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

tan (a) + cot (a) = csc (a) sec (a)

\frac{sin ( x )}{1 - sin ( x )} + \frac{sin ( x )}{1 + sin ( x )} = \frac{2 tan ( x )}{cos ( x )}

1 + cot^{2} (θ) = \frac{sec ^{2} ( θ )}{sec ^{2} ( θ ) - 1}
