Link to worksheets used in this section. We should expect, whenever we look at an operation that is used a lot in the business world, that Excel will have a fairly simple command to achieve the result. In section 1. In the last section, we noted that one can find candidates for a local maximum or minimum of a function by finding the derivative and using Goal Seek to find where the derivative is 0. In this section we introduce Solver, an Add-In to Excel. It is easiest to think of solver as a more powerful version of Goal Seek.
How to Find Local Extrema with the First Derivative Test
Find the Local Maxima and Minima -(x+1)(x-1)^2 | Mathway
You then use the First Derivative Test. This test is based on the Nobel-prize-caliber ideas that as you go over the top of a hill, first you go up and then you go down, and that when you drive into and out of a valley, you go down and then up. This calculus stuff is pretty amazing, eh? These three x- values are the critical numbers of f. Additional critical numbers could exist if the first derivative were undefined at some x -values, but because the derivative. Because the derivative and the slope of f equals zero at these three critical numbers, the curve has horizontal tangents at these numbers.
