The only you need in last question is to remember that ...
Find the indefinite integral.
I know you have to use U substitution U=1/x^5 but I get lost from there.
Find the derivative of y with respect to x.
I was told to use the product rule on this one but again I'm stuck.
Use implicit differentiation to find dy / dx.
Lost on how to find the derivative of ln(xy)
thanks in advance for any help.
