(In other words the derivative of x3is 3x2) So it is simply this: "multiply by power then reduce power by 1" It can also be used in cases like this: Example: What isddx(1/x) ? 1/x is alsox-1 We can use the Power Rule, where n = −1: ...

To find the derivative of ln(x), the first thing we do is let y = ln(x). Next, we use the definition of a logarithm to write y = ln(x) in logarithmic form. The definition of logarithms states that y = log b (x) is equivalent to b y = x. Therefore, by the definition of...
