Question

Evaluate:

Answer 1

what to ??

Answer 2

I am looking for the symbol hold on a minute

Answer 3

ok

Answer 4

u can even type the name of symbol

Answer 5

\[\int\limits_{?}^{?} (8x^6 - 7x +7) dx\]
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.

Answer 6

easy... u integrate all three terms firstly

Answer 7

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

Answer 8

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

Answer 9

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.

Answer 10

Where did the 2 come from

Answer 11

now u plug in upper limit value - lower limit value

Answer 12

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

Answer 13

x means x raised to the power 1

Answer 14

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

Answer 15

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

Answer 16

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?

Answer 17

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

Answer 18

someone fan me plss..

Answer 19

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

Answer 20

+7x

Answer 21

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

Answer 22

yes...
