    This is the second post I've seen like this in the past few days. No offense to you or anyone else, but give me a fucking break. BHW isn't here to help with math homework. I say take it to a specific homework helping forum/math forum.

    I think these threads should not be allowed.

    I can't make out the first or third one at all. These are relatively easy to solve though I can do them if you want.

    If this is out of a textbook check out www.cramster.com for 15 you can get a year long membership.

    The member's lounge is for random threads about pretty much whatever. If you don't want to read a post about math try not clicking on the thread!

    I love math.

    All 4 questions, 20 bucks.

    What math level is this, pure or applied 30?

    Alright I can't make out problem 1.

    Problem 2 involves using the Trapezoidal Rule which is explained here: http://en.wikipedia.org/wiki/Trapezoidal_rule

    Problem 3 I can't make out.

    Problem 4 involves using Riemann sums on a closed interval to get an area approximation. It is explained here: http://en.wikipedia.org/wiki/Riemann_sum

    I'm not actually going to do these because they are pretty straightforward when you read up on them. Don't you have a textbook with these problems that explains everything?

    Is that Calc 2 ? Since, Calc 1 mostly consists of Derivatives and Antiderivatives and some limits.

    I used to be able to do this shizzle fairly easy & quickly....About...5 years ago. You tend to become rusty when you don't touch calculus after a while lol. There are certain rules for it; follow them.

    Good luck though

    http://i48.tinypic.com/34t2ts0.jpg For this problem;
    You derive for f'( x ) = -3x^2 + 5 ...You plot for this negative parabola and submit for X = 0 and X = 2 ....Then I can't remember the rest.

    Thats wrong. You integrate.

    Thats why you need to use the Riemann definition of an integral.

    Look at my Wikipedia link.

    1.

    I can't read enough of it, does she need them all done?


    2.

    Answer: 19635

    Trapezoid rule = h/2 * (f(X0) + f(X1))

    h = X1 - X2

    In this case, the separation = 15 ft = h

    h/2 = 7.5

    The line lengths are the f(x)'s

    The area for 1st section = 7.5 * (85 + 125)
    The area for 2nd section = 7.5 * (125 + 137)

    Total area = 7.5* (85 + 125 + 125 + 137 + 137 + 149 + 149 + 141 + 141 + 139 + 139 + 140 + 140 + 141 + 141 + 132 + 132 + 127 + 127 + 71)
    = 19635




    3. Assuming I can read it right, it says the side is 3.0 inches

    Answer: +- 0.27 inches^3

    x = 3 inches
    dx = 0.01 (the possible error)

    V = x^3 (volume)

    dV = 3x^2 dx (This is the derivative of Volume, also the error)
    = 27 * 0.01
    = 0.27




    4.


    Answer: 5.75

    You take the rieman sum with 4 intervals.

    Divide it into 4 rectangles, x=0 to x=0.5, x=0.5 to x=1, x=1 to x=1.5, x=1.5 to x=2

    Area of each rectangle = x*y

    Because it wants the lower sum you use the lower values of x (0, 0.5, 1, 1.5)

    Area1 = 0.5 * (0*5 - 0^2)
    Area2 = 0.5 * (0.5*5 - 0.5^2)
    Area3 = 0.5 * (1*5 - 1^2)
    Area4 = 0.5 * (1.5*5 - 1.5^2)

    Sum = 5.75

    Guess I'd get a big F if I sat in a higher level math class again without practice...However, I could sign the paper with $-signs.

    Thread moved to the Hire a Freelancer section.

    I understand that the lounge may have looked like the proper section, but as soon as you offered something in return for work, it's not longer lounge material.
