Can you do the 3 hr video as well?

[@GodSavetheWest]

Keep doing this please!!!!! I am graduating this year and with COVID-19 I bet you're going to be needed. Thank you so much!!!!

[@revisionvillage]

Hello! Can u use integrating factor to solve for question 4 too?

[@gulmehekkhan5421]

At 7:05, why don't we write the derivative to be 2x+C, and we only write 2x? When do we know when to include it or not?

[@fiftyfive1s410]

You'll include it for all indefinite integrals. In this particular case, see the integrating factor as sort of a set formula, just know you don't need it there (it's because it gets sorted out when you add c at the end.)

what does A stand for??

[@dhikshithbalaji1714]

A is a contant (A=e^c)

[@sham550]

@@dhikshithbalaji1714 why does it get multipled all of a sudden instead of added? plus e^c is not times e^c right

[@niya.s.]

Because e^[ln(x) +c] is the same as [e^ln(x)]*[e^c] = [e^ln(x)]*A, because A=e^c. You apply exponent laws.
