Trigonometry

$\frac{- 5 π}{2}$

Convert the radian measure to degrees.

Tap for more steps...

To convert radians to degrees, multiply by $\frac{180}{π}$ , since a full circle is $360 °$ or $2 π$ radians.

$(\frac{- 5 π}{2}) \cdot \frac{180 °}{π}$

Cancel the common factor of $π$ .

Tap for more steps...

Factor $π$ out of $- 5 π$ .

$\frac{π \cdot - 5}{2} \cdot \frac{180}{π}$

Cancel the common factor.

$\frac{π \cdot - 5}{2} \cdot \frac{180}{π}$

Rewrite the expression.

$\frac{- 5}{2} \cdot 180$

Cancel the common factor of $2$ .

Tap for more steps...

Factor $2$ out of $180$ .

$\frac{- 5}{2} \cdot (2 (90))$

Cancel the common factor.

$\frac{- 5}{2} \cdot (2 \cdot 90)$

Rewrite the expression.

$- 5 \cdot 90$

Multiply $- 5$ by $90$ .

$- 450$

Convert to a decimal.

$- 450 °$

For angles smaller than $0 °$ , add $360 °$ to the angle until the angle is larger than $0 °$ .

$270$

The angle is between the third and fourth quadrant.

Between Quadrant $3$ and $4$
