prove-sin(pi/4)=-cos(pi/4)

prove

- sin (\frac{π}{4}) = - cos (\frac{π}{4})

True

Solution steps

- sin (\frac{π}{4}) = - cos (\frac{π}{4})

Manipulating left side

- sin (\frac{π}{4})

Simplify

= - \frac{2}{2}

Manipulating right side

- cos (\frac{π}{4})

Simplify

= - \frac{2}{2}

We showed that the two sides could take the same form

\Rightarrow True

tan (x) + cot (x) = tan (x)

tan (α + \frac{π}{4}) + tan (α - \frac{π}{4}) = 2 tan (2 α)

csc (0) cos (0) = cot (0)

(csc (x) - cot (x)) (1 + cos (x)) = sin (x)

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