so in order to find 

arcsin

arctan

arccos 

(the inverse to your three main trig functions)

you have to remember SOH CAH TOA

sin=Opposite/hyptoenuse  so arcsin= hypotenuse/opposite

cos= adjacent/hypotenuse so arccos= hypatenuse/adjacent

tan= opposite/adjacent       so arctan= adjacent/opposte

 

(arcsin can be written sin^-1 as can the others)
