prove-sin^2(x)=cos^2(x)-1

prove

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

True

Solution steps

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

Manipulating right side

cos^{2} (x) - 1

Rewrite using trig identities

= - sin^{2} (x)

We showed that the two sides could take the same form

\Rightarrow True

cos (x) + sin (x) (tan (x)) = sec (x)

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

\frac{1 + cos ( θ )}{sin ( θ )} = csc (θ) + cot (θ)

tan^{2} (θ) = sec^{2} (θ) - 1

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