Our teacher simply tells us to memorize a chart of derivatives. This is all fine and dandy, until it came to our last test and I am lost.
I know [tex]d sqrt{X}=1/2X[/tex] and [tex]d 1/X^2=-2/X^3[/tex]
However, I don't know why that is, and it doesn't give me way to handle derivatives for cube roots, etc.
For example, what would the derivative of [tex]sqrt[3]{X^5}? [/tex]
Thanks for the help.
EDIT- apparently I'm not so adept at the Latex code. That last one should be cube root of X^5
