this is the end part of a question and i dont understand the final integrating part. now Y.IF = / Q.IF dX (/ = THE INTEGRATION SIGN) THEREFORE Y (1X^2)^1/2 = / (1/1X^2).(1X^2)^1/2 dX Y.(1X^2)^1/2 = / (1/(1X^2)^1/2 dX / (1/(1X^2)^1/2) dX = SIN^1 X + C Y.(1X^2)^1/2 = SIN^1 X + C The bit that i do not get is how did they get from / (1/(1x^2)^1/2) dX = sin^1 x + C i cant see how they integrated to get to sin1 x, is there a method that i do not know? thank you for helping!
