Trigonometry Examples

$\frac{1}{2} x + \frac{π}{2} = 0$

Step 1

Combine $\frac{1}{2}$ and $x$ .

$\frac{x}{2} + \frac{π}{2} = 0$

Step 2

Subtract $\frac{π}{2}$ from both sides of the equation.

$\frac{x}{2} = - \frac{π}{2}$

Step 3

Since the expression on each side of the equation has the same denominator, the numerators must be equal.

$x = - π$

Step 4

The result can be shown in multiple forms.

Exact Form:

$x = - π$

Decimal Form:

$x = - 3.14159265 \dots$
