implicit differentiation activity pdf

Implicit differentiation is a technique that we use when a function is not in the form y=f(x). Find dy dx, given (3xy+7)2 = 6y: Solution: Take the derivative with respect to xof each side of the equation. /Border[0 0 0]/H/N/C[.5 .5 .5] /Type /Annot /Border[0 0 0]/H/N/C[.5 .5 .5] /Type /Annot Math 100 – WORKSHEET 10 IMPLICIT DIFFERENTIATION; INVERSE TRIG FUNCTIONS 1.
