prove 3+3cos(x)=2(1-cos^2(x))

prove

3 + 3 cos (x) = 2 (1 - cos^{2} (x))

False

Solution steps

3 + 3 cos (x) = 2 (1 - cos^{2} (x))

Show that the two sides are not equal

\Rightarrow False

\frac{tan ( x ) + sin ( x )}{1 + sec ( x )} = sin (x)

\frac{cos ( 3 a ) cos ( 2 a )}{sin ( 3 a ) sin ( 2 a )} = \frac{cot ( 2 a )}{tan ( 3 a )}

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

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

sin (b) cos^{2} (b) - sin (b) = - sin^{3} (b)
