prove cos(pi/2)+1=sin(pi/2)

prove

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

True

Solution steps

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

Manipulating left side

cos (\frac{π}{2}) + 1

Simplify

1 + cos (\frac{π}{2}) : 1

= 1

Manipulating right side

sin (\frac{π}{2})

Simplify

= 1

We showed that the two sides could take the same form

\Rightarrow True

\frac{cos ^{2} ( θ )}{sin ( θ )} = csc (θ) - sin (θ)

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

\frac{sin ( 2 x )}{2} = cos (x) sin (x)

\frac{1 + tan ^{2} ( x )}{cot ^{2} ( x ) + 1} = tan^{2} (x)
