What an exercise! You don't know how much it helped me make a similar one; I apreciate it. But if you can help me answer this question that would be great; If you have here 3^x cosx dx + ln(3)^2 because it gave you 1+ln(3)^2, if you are using variable isolation; So how did you manage to get to this?. I thank you in advance

sorry, i didn't understand your question. you wrote: If you have here 3^x cosx dx + ln(3)^2 well... if you definitely meant this ln(3)^2 is a constant and therefore, its integral will be ln(3)^2 multiplied by x. well... i think you didn't mean this. either you mistyped something or I am not getting you. please elaborate.

great vid helped me a lot with the problem just use a stylus nxt time its easier than .math

WHY DOES THE WORD "ILATE" NOT GET THE RESULT?
