prove (1-cos(θ))+sin^2(θ)=2

prove

(1 - cos (θ)) + sin^{2} (θ) = 2

False

Solution steps

1 - cos (θ) + sin^{2} (θ) = 2

Show that the two sides are not equal

\Rightarrow False

\frac{1}{sec ( θ )} = (sec (θ))^{- 1}

sin^{2} (2 x) = \frac{1}{2 ( 1 - cos ( 4 x ) )}

sin (2 θ) + cos (2 θ) = 1

25 (sec^{2} (5 x) - tan^{2} (5 x)) = 25

cot^{2} (x) = \frac{( cos ^{2} ( x ) )}{1 - cos ^{2} ( x )}
