Here's what I would do without a calculator or a knowledge of the arcsin function. It's a crude kind of what's called a numerical method. Suppose I wanted to solve sin x = 7/16.
7/16 = .4375
I'd make a guess:
sin 45(degrees) = .707 (make a smaller guess)
sin 20 = .342 (make bigger guess)
sin 30 = .5 (go between 20 and 30)
sin 25 = .423 (go between 25 and 30)
sin 26 = .438
... and so on.
