**The Definition of the Derivative S.O.S. Math**

Hence, the directional derivative is the dot product of the gradient and the vector u. Note that if u is a unit vector in the x direction, u=<1,0,0>, then the directional derivative is simply the partial derivative with respect to x. For a general direction, the directional derivative is a combination of the all three partial derivatives.... Can you describe the epsilon delta definition of limits, compared to other definitions? How can we understand the epsilon-delta definition of a limit more easily? Why do mathematicians choose the delta-epsilon definition to be the limit of a function?

The derivative of x² at x=3 using the formal definition The derivative of x² at any point using the formal definition So let's think about how we could find the slope of the tangent line to this curve right over here, so what I have drawn in red, at the point x equals a. And we've already seen...The most basic way of calculating derivatives is using the definition. This involves calculating a limit. To calculate derivatives this way is a skill. As with any skill, you only improve with practice. We talk at length about how to use the definition on the page calculating the derivative by definition. The Chain Rule. The chain rule is the most important rule for taking derivatives. With

- Definition. Let y = f(x) be a function. The derivative of f is the function whose value at x is the limit provided this limit exists. If this limit exists for each x in an open interval I, then we say that f is differentiable on I.
