    Ok here's 12a, I found a mathcad sheet online to calculate it as I couldn't remember enough about Riemann sums from Calc 1 or 2 or whenever the hell I learned them to do it by hand or check that this is right. From what it graphed I think it's doing it right

    Here's the MRAM method for 12b

    I can send these to you if you have Mathcad, check to make sure I didn't misread any of the variables or anything in your picture. You can recreate the work in it by following through and substituting all the variables in as they get reassigned to each other

    Hopefully Kona will chime back in for #13 but IIRC you just have to find the definite integral of it, right?

    If so,

    10 years ago for me.


    To the OP:

    Rest assured once you get out of school you will never use this crap again!

    if one goes into a career in science/math/engineering, ...it is fundamentally important, ...and that goes for the real world too ;)

    I took this class in spring semester... got an A. Just finished a summer physics course last week... got a B.

    Already forgot how to do this shit, though. haha.

    I used to be so good at Calc... but no it's brutal to try and decipher.

    For example, your post made my right hemisphere and left nut unravel.

    It's not even once you get out of school... Once you squeak your way through calc classes you never use anything but the simplest derivatives and integrals (at least so far, I know I got some classes coming up that are gonna require Diff Eq)

    And from my work experience so far all the calculations are done by Mathcad and not much hand calculations are done. Granted, I'm only halfway through my Mechanical Engineering degree and this is just coming from a few internships.

    Anywho, lemme know if I was right OP. No guarantees though :p
