The Derivative
The derivative of f(x) can be written as f '(x), or more commonly when y = f(x), dy/dx. The equation shown earlier in the tangent to the curve can be generalized.
The derivative of a constant, such as 1, 2, 3.. 2/9, sqrt(3), etc is 0. | |
The derivative of y = mx+b is m, the slope of the line y. | |
The derivative of a term x raised to a power n is just as shown. |
