I did...but I keep getting 5e^2 I think its differentiating that's the problem. Can you help with that?

Thankyou so much! I can do it now =] all that was needed was that rule you gave for differentiating e to the power of a function. Thank you! Anthmoo

I got ...that's right isn't it? Thanks =]

Does look like ? Recall what Jhevon said: Originally Posted by Jhevon also recall that , where is a function of Here we have . So what is ? -Dan
