i got 1/3x^2 + 2
why am i wrong....answer...make use of this site...i asked multiple questions and got no reply...
Again, I am sorry I did not see this post till now. The system does not seem to alert me when someone has posted a question.
Here is my answer: When you differentiate this you have to use the chain rule: so you get the derivative of the "outer" function (of the ln function) evaluated at the "inner function" (x^3+2x-7), multiplied by the derivative of the inner function (i.e. 3x^2+2).
Thus the answer is
[1/(x^3+2x-7)]*(3x^2+2)
