Hi!
This shouldnt be hard but for some reason itīs giving me problem.
f(x) = 1 / (x+1)
How do I find the F(x) for this function?
Thanks
Because of the Chain Rule, you must carry out the derivative of what's inside the natural log. In this case, it is 2, so $\displaystyle f(x)=\frac{2}{2x+2}$. To make this adjustment for the integral of $\displaystyle f(x)=\frac{1}{2x+2}$, you must divide the integral by 2, so you have an answer of $\displaystyle F(x)=\frac{\ln(2x+2)}{2}$.
