prove (sin(θ))^2+(cos(θ))^2=1

prove

(sin (θ))^{2} + (cos (θ))^{2} = 1

True

Solution steps

(sin (θ))^{2} + (cos (θ))^{2} = 1

Use the Pythagorean identity:

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

\Rightarrow True

tan^{2} (π) = tan (π)

\frac{( - 1 + sec ^{2} ( b ) )}{tan ( b )} = tan (b)

cos (- θ + \frac{π}{2}) = sin (θ)

- 1 - cot^{2} (x) = - csc^{2} (x)

sin (2 x) + cos (x) = 0
