Example Question #442 : Functions
What is the slope of the function at point
?
To consider finding the slope, let's discuss the topic of the gradient.
For a function , the gradient is the sum of the derivatives with respect to each variable, multiplied by a directional vector:
It is essentially the slope of a multi-dimensional function at any given point
The approach to take with this problem is to simply take the derivatives one at a time. When deriving for one particular variable, treat the other variables as constant.
The function we'll evaluate is
Take a derivative with respect to each variable and determine the value for the point
