Many and more students who study any branch in mathematics face a lot of troubles. And calculus is one of these problems. Trying hard to learn all the formulas the students finish up with a huge number of calculus questions that cause many problems in the studying process. We have worked out our service system so that you could get the calculus answers any time you need them with a minimum waste of time. If you have nobody to help you with the calculus problems – we are at your disposal!

Calculus

(a) Create a function that is a product of two non-constant functions that would NOT require the product rule to differentiate it.

(b) Differentiate your function from part (a) without using the product rule.

(c) Differentiate your function from part (a) by using the product rule and confirm your result is equivalent to your result in part (b) by simplifying.
