I have to convert −14.8° into radians, expressing my answer as exact values and as approximate measures (to the nearest hundredth of a radian).
This may be a very elementary question, but I'm not sure how express my answer in exact values?
I got −7.490π using the conversion factor of π180° and dividing −14.8° and by 2.
However, the textbook got . That means was used to multiply and . Why 2.5? How did the textbook get this number?
Thank you! :)
