prove sin(t)=cos(t-pi/2)

prove

sin (t) = cos (t - \frac{π}{2})

True

Solution steps

sin (t) = cos (t - \frac{π}{2})

Manipulating right side

cos (t - \frac{π}{2})

Rewrite using trig identities

= sin (t)

We showed that the two sides could take the same form

\Rightarrow True

\frac{1}{2 cot ( x ) sin ^{2} ( x )} = csc (2 x)

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

cos (α + β) - cos (α - β) = - 2 sin (α) cos (β)

\frac{cot ( x )}{sin ( x )} = 1

7 sec (θ) = \frac{7 sec ( θ ) - 7}{1 - cos ( θ )}
