Calculus - Differentiation - the Product Rule.
Test Yourself 1.
Differentiate each of the following equations using the Product Rule with respect to the relevant pronumeral:
No rule. | 1. | y = 3x4 (2x - 5) | 2. | |
One bracket. | 3. | y = x (2x + 4)4 | 4. | s = t3 (3t + 1)3 |
5. | y = (4 - 3x)5 x4 | 6. | V = (1 - 2r)3 4r | |
Two brackets - could expand but do as product rule for practice. | 7. | y = (2x + 3)2(x - 4) | 8. | m = (n3 + 5)2(4n - 1) |
Two brackets - higher power - proper Product Rule:) | 9. | y = (x + 3)(x - 2)5 | 10. | V = (4 - r)(1 - 2r)3 |
11. | Given that f(x) = (x+1)(x-1)5,
find the values of a and b such that f '(x) = (ax+b)(x-1)4. |
y = x4(x + 1)3 | ||
Two brackets - both with powers. | 11. | y = (2x - 1)3 (x - 3)2 | 12. | D = (x + 1)3 (x + 2)2 |
Surds. | 13. | 14. |
