In this problem, WeBWorK will not accept as answers mathematical expressions that involve the trigonometric functions or their inverses. You need to enter numbers.
In this problem we measure angles in degrees. The inverse sin function returns an angle between -90 and +90 degrees. This gives perhaps surprising results when you evaluate the sine somewhere and then the inverse sine at the result. You can just key the problems below and in the following problems into your calculator, but try to get them without a calculator. If you yield to temptation and do use your calculator, at least think about the answers when they are unexpected.
Complete the following equations:
$\arcsin(\sin(37^\circ))=$ ${}^\circ$,
$\arcsin(\sin(-25^\circ))=$ ${}^\circ$,
$\arcsin(\sin(100^\circ))=$ ${}^\circ$,
