Need Calculus help
I don't know how well this will work, but I've seen people get help on here before, so I guess I'll try it. Anyways, I'm in Calculus 1, I can't get to the tutoring center at community college, I missed 50 minutes of the last class and I'm confused as hell on the Fundamental Theorem of Calculus
1.) Integral 1 to 3 (X-1) ((X^2)+X+1) dx
2.) Integral 0 to 1 (X+3)/squareroot((X^2)+6X+2) dx
3.) Integral 2 to 6 1/(5X+7) dx
I've gotten partway through problem 1, broke it into two parts and got
((u^2)/2)+c -1/X times ((u^2)/2)+c
And now I'm stumped.

Think I've gotten all the way through #3 correctly. Made u=5X+7, du=5dx, du/5=dx =Integral 17 to 37 (1/u)(du/5) =1/5 Integral 17 to 37 (1/u)(du) =1/5 ln [b]l[/b]u[b]l[/b] g(37) - g(17)= 1/5 ln [b]l[/b]37[b]l[/b] - 1/5 ln [b]l[/b]17[b]l[/b] =0.15554 Don't care if nobody reads this, Flood learn some math.
