It has all these functions, and most of the rules of calculus are built in. But for some reason they skipped out on the product rule. This would cause alot of problems in my Differential Equations class. Can anyone tell me how to program the product rule into my 89 without messing with any other part of the program? Thank you.
 
Doesn't the 89 automatically differentiate using the product rule?
Isn't everything under F3?

The product rule is not hard and you might struggle in Diff Eq. if you have trouble memorizing the product rule.
