Question

derivative of v(t)= t^2e^(-ct)

Answer 1

use the product rule
v' = t^2 * -c * e^(-ct) + e^(-ct)* 2t
= te^(-ct)(2 - ct)

Answer 2

how would you solve using the chain rule?

Answer 3

you cant because its the product of two functions
i used the chain rule to differentiate e^(-ct)
= -c * e^(-ct)
