find the derivative of y with respect to x, t or theta as appropriate. y= ln(x)/x^6
\[y=(x^{-6})*\ln x\] Use the product rule (derivative with respect to x) \[y'=(x^{-6})*(\frac{1}{x})+(\ln x)*(-6x^{-7})\]
the answer is 1-7 ln(x)/ x^7 how can u get that?
Simplify from what I typed and you should get the exact same answer. Remember that \[x^{-a} = \frac{1}{x^a}\]
