Product rule formula - The Formula

We then subtract the next element down on the left, multiplied by the element that the cross points to here as well.

Computational feasibility significance Each of the versions has its own computational feasibility significance: Version type Significance specific point, named functions This tells us that knowing the values in the sense of numerical values of and at a point allows us to compute the value by plugging into the formula and doing a bunch of multiplications and additions.
