i'm talking about the formula that says the integral of f'(x)/f(x)dx = ln(f(x))+C

it's kind of hard to put this into Google. where does this formula come from, and can i derive it using basic math i would know (algebra, calculus, etc.)? any way there is of showing why this formula is true would be appreciated ... i like to see multiple demonstrations if they exist.
