So I have been using the limit definition of the derivative that involves h, and I have to find the derivative 1/(x+3) So I set the top to have common denominators, and then simplify a bit. I end up with 3/((x+h)(x+h+3), all of which is over h. I know this isn't correct. I'd go into greater detail but the math would look really ugly. How do I solve this? Do I use the other limit definition of the derivative?
