Trigonometry Examples

$\sin (π - x) = \sin (x)$

Step 1

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

$x \approx 0, - 0.1, 0.1, \frac{2}{5}, \frac{1}{2}, \frac{3}{5}, - \frac{11}{5}$

Step 2

The result can be shown in multiple forms.

Exact Form:

$x \approx 0, - 0.1, 0.1, \frac{2}{5}, \frac{1}{2}, \frac{3}{5}, - \frac{11}{5}$

Decimal Form:

$x \approx 0, - 0.1, 0.1, 0.4, 0.5, 0.6, - 2.2$

Mixed Number Form:

$x \approx 0, - 0.1, 0.1, \frac{2}{5}, \frac{1}{2}, \frac{3}{5}, - 2 \frac{1}{5}$
