Evaluate the following derivatives using the chain rule:
1. (d/dx) In(3x^2+9x+4)
2. (d/dx) [(2x+4)/(3x-1)]^3
1.)
[1/(3x^2+9x+4)]* (6x+9)
2.) 3[(2x+4)/(3x-1)]^2 * [ (2(3x-1) - 3(2x+4))/(3x+1)^2]
if you're intrested in actually learning how to do this let me know and I'll teach you, not really hard. Looks much much worse than it is. If you learn how to do thus it will save u during an exam while just copying answers will not get u anything in the long run (not to mention the answers you copy could be wrong...).
hope to hear from you.
