Question

Show the process to evaluate the integral, int(x^3+x)/(x) dx, on the int, a 3 is on top and a 1 is on the bottom

Answer 1

divide both terms by x : x^2 + 1
integrate each term seperately (1/3)x^3 + x
substitute 3 for x and then 1 and subtract the results

Answer 2

yeah, split the fraction into ist parts...

Answer 3

\[\int\limits_{} \frac{x^3}{x}+ \frac{x}{x}dx\]

Answer 4

okay, so would 4 be the answer

Answer 5

from [1,3]

[S] x^2 + 1 dx -> x^3/3 +x

F(1) = 4/3 ; F(3) = 12

12 - 4/3 = 12 - 1'1/3 = 10'2/3

Answer 6

I get 10' 2/3 ; or 32/3

Answer 7

so no help...just checking
