prove 2cos^2(x)=2cos(x)cos(x)

prove

2 cos^{2} (x) = 2 cos (x) cos (x)

True

Solution steps

2 cos^{2} (x) = 2 cos (x) cos (x)

Manipulating right side

2 cos (x) cos (x)

Simplify

2 cos (x) cos (x) : 2 cos^{2} (x)

= 2 cos^{2} (x)

We showed that the two sides could take the same form

\Rightarrow True

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

csc (\frac{π}{2 - x}) cot (x) = csc (x)

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

(3) \frac{( cos ^{2} ( 2 z ) )}{2} = \frac{3 cos ( 4 z )}{4}

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