Derivative of constan t We could also write and could useB B-. Then as Dx heads towards 0 we get. Then the function f x is said to be differentiable at x0 and the derivative of f x at x0 is given by.
We also cover implicit differentiation related rates higher order derivatives and logarithmic.
The derivative of x2 is 2x. The derivative is often written as dy over dx meaning the difference in y divided by the difference. Note that we replaced all the a s in 1 1 with x s to acknowledge the fact that the derivative is really a function as well. 2x Dx.
