Hi there
Getting stuck on this equation.
e^(-x) / ln(x)
Solving it by quotient rule, however answer has extra x in numerator.
using the dy/dx = (v(du/dx)-u(dv/dx))/v^2
dy/dx = (ln(x)*-e^(-x) - (-e^(-x)*1/x)/ln(x)^2
Answer = (-e^(-x) (x ln(x)-1))/x(ln(x))^2
Would appreciate help with breaking this down. Cheers
