Question

how do you do integral on x^3-2x-x

Answer 1

When you have a sum or a difference under the sign of an integral, you can split it into many integrals. By doing so, you will have three different integrals, but they will be easy to calculate.

Answer 2

1/4x^4- 2/2x^2-1/2x^2 is that right?

Answer 3

Yes, this is correct, and of course you need to add the arbitrary constant C to your final answer.

Answer 4

+ C o ok and can it be simplyfied in any way?

Answer 5

well, 2/2=1 and you could factor out x^2.

Answer 6

You should simply x^3 - 3x prior to taking integral!

Answer 7

i have 1/4 X^4-3/2 x^2 in my textbook as an answer I don't see how they got there

Answer 8

i have no clue what you did there

Answer 9

no how did you get there

Answer 10

1/4x^4- 2/2x^2-1/2x^2 < how does that get to x³- 3x

Answer 11

1/4 X^4-3/2 x^2 is the answer i have in my book

Answer 12

yesss

Answer 13

ah!

Answer 14

∫ x³ dx = x^4/4
- 3∫ xdx = -3x²/2

Answer 15

-2x-x= -3x

Answer 16

i see it now very simple

Answer 17

thank you very much

Answer 18

Yup, indeed it issss!
