## anonymous 5 years ago what is derivative of y*ln(x+y-2)

1. anonymous

are you looking for derivative in terms of x or y?

2. anonymous

well the derivate of Ln is 1/x Just reemplace

3. anonymous

implicit diffr.

Product rule: derivative (a*b) = derivative a * b + a * derivative b (y*ln(x+y-2)) ' dy/dx * ln(x+y-2) + y * (1 + dy/dx) * 1 / (x+y-2)

product rule $y'*\ln(x+y-2)+y*(1+y')/(x+y-2)$

that is it!
