$\cot (x - \frac{π}{2}) = - \tan (x)$

Step 1

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

$x \approx 0, 0.1, - 0.3, 0.3, - \frac{2}{5}, \frac{2}{5}, \frac{1}{2}$

Step 2

The result can be shown in multiple forms.

Exact Form:

$x \approx 0, 0.1, - 0.3, 0.3, - \frac{2}{5}, \frac{2}{5}, \frac{1}{2}$

Decimal Form:

$x \approx 0, 0.1, - 0.3, 0.3, - 0.4, 0.4, 0.5$
