: : I'm currently taking Calculus II after taking Calculus I four years ago and I find that I can't remember the simplest things.
: One of the simplest things to remember (since you forgot) is to look in your textbook. there are few (and I mean few) calculus texts that do not have basic derivative lists either on the inside covers or first chapter.
: however, I'll be easy on you this time...
: the derivative of 1/x (with respect to x) is ln(x) provided x > 0.
You're incorrect, the derivative of 1/x is 1/(x^2). ln|x|+ C is the integral of 1/x, I believe you are getting the two confused.
