Hi Guys, I'm a little stuck on how on to differentiate when equations involve e and ln. How would I go about differentiating y= e^x^2 ln x for instance ? Thanks for your help.

Thanks for your help. Please use parantheses for grouping! Which one of the following equations do you mean: y= e^(x^2)*ln (x) ---- > y= e^((x^2)* ln (x)) ---- > y= e^(x^(2* ln (x))) ---- >

I'll have to read up on how to use the correct math text. 2x*e^xsquared*1/x You can't just take the derivative of one factor and multiply it by the derivative of the other factor. As I said, we have to use this product rule: So your answer, before simplification, should have two terms.
