Calculus - Differentiation - the Quotient Rule.
Test Yourself 2.


 

Differentiate each of the following equations using the Quotient Rule:
No rule. 1.

Hint. The expression in the numerator is suspiciously like that in the denominator. The signs have been reversed.
So factorising out -1 makes the two terms the same and they cancel.
So what is the derivative of -1?
You could also apply the quotient rule to confirm your answer. This question came from a test paper!!
