$\tan (x - \frac{π}{2}) = - \cot (x)$

Step 1

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x \approx - 0.1, 0.1, - \frac{1}{5}, - \frac{4}{5}, - 0.9, 0.9, 1$

Step 2

The result can be shown in multiple forms.

Exact Form:

$x \approx - 0.1, 0.1, - \frac{1}{5}, - \frac{4}{5}, - 0.9, 0.9, 1$

Decimal Form:

$x \approx - 0.1, 0.1, - 0.2, - 0.8, - 0.9, 0.9, 1$
