Hi everyone!
I have two questions:
1. Is it possible to replace set for with set to?
2. Why are the plurals of degree and radian used in the sentence? I suppose, degree and radian only appear in their singular form in calculators.
Thanks a lot!

... The inverse sine function may be expressed as sin1762347120272.png(0.866), which is a shorthand way of asking the question "What angle has a sine of 0.866?" Punching a couple of buttons on your calculator reveals that this angle is 60.0°. Try it for yourself and show that tan1762347120272.png(0.400) = 21.8°. Be sure that your calculator is set for degrees and not radians. College Physics, Ninth Edition, by Raymond A. Serway and Chris Vuille
