Hello, Originally Posted by bart 1000 i have the function log (x^2+1) e and i believe the answer is 2x x^2+1 but i am not sure what steps to take to get the answer, can anyone help. Yes it is the answer But I don't understand why you want the steps... How did you get the answer, since it is correct ? In general, let f(x) be a function, The derivative of is, by using chain rule, And hence your result.
