Convert 75 Degrees to Radian Measure - 5/12 pi

[fatima_a]

convert 75 degrees to radian measure

the answer is 5/12 pi

i know that for converting degrees to radians you multiply the degrees by pi/180 degrees and when i do it i get the answer 1.3089... but how do you get the answer as above, in that form? i have changed the mode of my calculator from degrees to radians and vice versa but i can't get the answer in that notation.

Reduce 75$\pi$/180 and leave it in terms of pi; don't put it in the calculator.

Following Bohrok's advice, you basically never evaluate $\pi$ unless you are doing some sort of physical application where it's nice to have the approximate solution.
