How do you turn -15 degree into radians?

1 Answer

Oct 3, 2015

Use the fact that $180^{\circ} = π radians$ $180^@ = pi " radians"$
to get $- 15^{\circ} = - \frac{π}{12}$ $-15^@ = -pi/12$ radians

Explanation:

Since
$XXX 180^{\circ} = π$ $color(white)("XXX")180^@ = pi$ radians

$XXX 1^{\circ} = \frac{π}{180}$ $color(white)("XXX")1^@ = pi/180$ radians

and
$XXX - 15^{\circ} = (- 15) \cdot \frac{π}{180} = - \frac{1}{12} π = - \frac{π}{12}$ $color(white)("XXX")-15^@= (-15)*pi/180 =- 1/12pi = -pi/12$ radians
