u can even type the name of symbol
anonymous
  • 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.

  • anonymous
easy... u integrate all three terms firstly
anonymous
  • 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
anonymous
  • anonymous
integration of 8x^2= 8x^3/3 7x will be 7x^2/2 and 7 becomes 7x
anonymous
  • 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.

Where did the 2 come from
anonymous
  • anonymous
now u plug in upper limit value - lower limit value
anonymous
  • 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?
anonymous
  • anonymous
x means x raised to the power 1

He made a mistake. That's 8x^6 bro
anonymous
  • anonymous
oh sry that was 8x^6...my bad ...it will become 8x^7/7
anonymous
  • 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?
anonymous
  • anonymous
exaxtly , it is the 6 which has to be increased by 1 and divided by
anonymous
  • anonymous
someone fan me plss..
anonymous
  • 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
anonymous
  • anonymous
+7x
anonymous
  • anonymous
Oh, something just clicked, the 7 became an 7x because we are taking the derivative back to original problem?.?.? Is that correct?
anonymous
  • anonymous
yes...
