X^-1 = 1/X AND SIN^2 X = (SIN X)^2, SO SIN^-1 X SHOULD EQUAL 1/SIN X, I.E. CSC X. NO! SIN^-1 IS THE INVERSE FUNCTION, YOU'RE NOT ACTUALLY RAISING IT TO A POWER! THEN WRITE IT DIFFERENTLY AND KEEP YOUR NOTATION CONSISTENT! HOW? ARCSIN X? THAT JUST LOOKS STUPID! NOT AS STUPID AS AN EXPONENT! CALL IT ANTISIN X FOR ALL I CARE!
