what to ??

2. anonymous

I am looking for the symbol hold on a minute

3. anonymous

ok

4. anonymous

u can even type the name of symbol

5. anonymous

$\int\limits_{?}^{?} (8x^6 - 7x +7) dx$ That is the symbol but there are no numbers at the top or bottom. That was the closest to the symbol I could find on here. I really don't understand how to do this.

6. anonymous

easy... u integrate all three terms firstly

7. anonymous

That is what I am having trouble with. I am really lost. My brain is wanting to do derivatives and I don't think these work that way

8. anonymous

integration of 8x^2= 8x^3/3 7x will be 7x^2/2 and 7 becomes 7x

9. anonymous

indefinite integral, derp. Antidifferenciate it... if you didn't learn that there is no way the professor would ask it... That symbol is basically asking you to take the reverse of derivation. The area under the curve.

10. anonymous

Where did the 2 come from

11. anonymous

now u plug in upper limit value - lower limit value

12. anonymous

x means x raised to the power ..so after integrating u add 1 to it and then dividing it by 2 as well..ok?

13. anonymous

x means x raised to the power 1

14. anonymous

He made a mistake. That's 8x^6 bro

15. anonymous

oh sry that was 8x^6...my bad ...it will become 8x^7/7

16. anonymous

Just want to make sure I understand what I am doing, when there is an exponent, do I add 1 to it and then divide that number???? The 8 in 8x^6 really does nothing at this point, correct?

17. anonymous

exaxtly , it is the 6 which has to be increased by 1 and divided by

18. anonymous

someone fan me plss..

19. anonymous

So will the answer be 8x^7/7 - 7x^2/2 Do I do anything with the 7 at the end that has no x with it

20. anonymous

+7x

21. anonymous

Oh, something just clicked, the 7 became an 7x because we are taking the derivative back to original problem?.?.? Is that correct?

22. anonymous

yes...
