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.

Tut! Tsh! she don't know how to do that. Just sack her lmao.
I ain't got a clue what it even is.
Good luck.

Its the fucking lounge bro.

"homework helping forum" ? wtf...

take the tampon out of your ass and calm down.

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.

{EDIT} My calc class hasnt gotten this far yet... lol

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!

From the site description on the front page:

What's been on your mind lately? Maybe you've come across a website that made you laugh. Almost anything goes here!

Sorry, can't help you out... but man do I hate calculus.

nowimhere · Dec 15, 2009

I love math.

All 4 questions, 20 bucks.

What math level is this, pure or applied 30?

killzone · Dec 15, 2009

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?

truepals_forever · Dec 15, 2009

I wish those pics were more clear.. I could solve all calculus problems but I can't see those questions..

SNiiP3R · Dec 15, 2009

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.

**This is the lounge, get off my thread if you just want to talk shit**

And thanks guys, I still haven't got a clue but thanks for hopping on.

I will have her recopy the problems and post them in about 12 hours. I will post it on here so stay posted

I will pay $20 now once they are uploaded in about 12-18 hours

Keep posted and keep posting on here because I might PM you

She can have an extension to take it another day. I just don't know how to help her. I'm a stats person.

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.

blackmagiquellc · Dec 16, 2009

I have the problems written out now - PM me if you are interested

my girl needs them within 8 hours

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.
