30° + 180° (2n + 1), its radian measure is equivalent to?

Example:Find the radian measure of the angles −70° and 120°.

Solution:To find the radian measure of −70° we multiply −70 by the conversion factor /180. We get

Similarly, for 120° we obtain

Note that when we write an angle as a fractional amount of , for example 2/3 times  we write the result either as the numerator times  divided by the denominator or as the fraction times . So the two values

are equivalent ways of writing the same number. You will see both methods used in the text and in the exercises.

Example:Find the degree measure of /12.

Solution:The conversion factor for going from radians to degrees is 180/. We get

and so the radian measure of /12 is 15°.
