Question

Calculate dy/dx. Simplify your answer.
y = x^3(8-x^2)

Answer 1

I missed one day of class this week when they went over this lesson . . . so now I'm kind of behind . . . and don't completely understand the dy/dx concept yet. >_<

Answer 2

first expand
= 8x^3 - x^5
dy/dx = 24x^2 - 5x^4

Answer 3

oh I just multiply through, and then use the power rule?

Answer 4

use the stabdrad form:

if y = ax^n then dy/dx = anx^(n-1)

Answer 5

yes

Answer 6

Ohhhhh that makes perfect sense lol. Thank you very much!!

Answer 7

stabdrad = standard!

Answer 8

no probs
