## 3psilon 4 years ago More integral help. What would be the anti derivative?

1. 3psilon

$\int\limits_{1}^{4} \frac{ 8 }{ \sqrt{t} } -12\sqrt{t ^{3}} dt$

2. 3psilon

I entered this into wolfram and got a answer that was different from mine. And I didn't quite understand how it yielded that anti derivative

How did you get the t^5? @JoãoVitorMC

you might want ot convert the roots to rational exponents. it would probably e easier.

(3/2) + 1 = 5/2

8t^(-1/2)-12t^3/2

integrate that expresson
