oh, ok i get ya.. :) Alright thanks guys

oh, i see where i messed up with the switching on e-1 and the e-2. Ok, I'm getting -ln2 now since it will be 0-ln2 = -ln2 :approve: but I'm still confused... did i do anything else wrong? Or does it seem ok?

Homework Statement I have to find the definite integrals of some problems... I did them in paint because i do not know how to do it on the forum so sorry if that is a problem Here is the problem and my attempted answer. I think i got the first one right, but the second one, someone told me...

YEA! :) thanks so much for the help! I reaaaaaaaally appreciate it.

yea, i thought i had done something wrong so is this right now?

heh... yea, paint is a pain :cry:, but it's still easier than trying to figure out how to do it on this forum and my teacher told us we don't have to simplify, so I'm good :Done last thing to be sure... :P I'm right in that only the 2/10(1-x)10 is negative? I thought i had messed that one up...

ok thanks :biggrin:, but now I'm a little lost on what to do now with this... i tried to change it since i have a new equation but i think I'm doing something wrong. either I'm doing the signs wrong, or something else, but it just doesn't seem right here is what i got

yea, i thought that was wrong... I've always sucked at doing this.. so (1-u)2=u2-2u+1 then, u8(u2-2u+1) right? would it be u8-2u9+u10

Homework Statement Well, i didn't know how to do anti-derivatives on this forum so i just did it on paint :) Anyways, here is the problem and solution i tried. Let me know if i did anything wrong, or if i even did anything right... Thanks a lot! i have to find the anti derivative of ...

i wasn't sure. Like i said, i had never done integrals before so i just looked at another problem and tried to copy the steps that it took to solve. Constant made the most sense so that's what i guessed it was.

great! Thank you so much :biggrin:

oh... so then it would be u[x-1+1]? then the -1 and 1 cancel out, and you get u[x]

i actually assumed it should be equal :) I'm really bad at simplifying, but i thought it should equal that.

(x-1)8+(x-1)7 => (x-1)7x (im guessing the c is a constant?) we never learned the fundamentals of integration :) We are going to learn them today, this is just a problem she gave us and said to try to solve it on our own. (like a heads-up kind of thing) I just looked up an example...

Oh, ok, but how do i differentiate the c and what do i do to bring back the x when i differentiate? (since i changed the x to u+1)
