You should solve your test alone, am I right ?
Hi, guys. I'm working on a take-home test for my Calculus 1 class.
The first part of the problem was
"Find the area under f(x)=2x^2-x from 1 to 2 using the definite integral (not FTC)."
I ended up with 18/6.
However, for the second part of the problem, "Compute the definite integral from 1 to 2 (using the antiderivative squiggle) (2x^2-x)dx using the Fudamental Theorem of Caluclus," I got 33/6.
I feel like I probably did the FTC part correctly because it is much less complicated.
But, if you think I'm wrong, please let me know, and show me what I should do!
I'm attatching files showing the work I did since it's far too complex to type.
I understand it might be a little difficult to read, but I just hope you can get the just of what I did
Thank you for catching that!
I also noticed I messed up while taking the limits and adding up the fractions for the first part, 19/6 is the correct answer.
I so much appreciate your help in going through that for me, I would have NEVER caught that mistake I made in FTC!
