Please explain inverse functions. i.e.
find angle if Sin x = 2.3 divided by 8.15. Answer 16.30 degrees. How did they do that???
2.3/8.15 = 0.28221
sin^-1 0.28221 = 16.39 degrees
That means sin 16.39 degrees = 0.28221
You need a trig table of the sine function, or a pocket calculator to get the answer.
