# Big Accomplishment of the Day

Posted 29 May 2009 - 07:14 AM

This is mine *swoons* First try too.

The question:

Consider t he following problem: A box with an open top is to be constructed from a square piece of cardboard, 3 ft wide, by cutting out a square from each of the four corners adn bending up the sides. Find the largest volume that such a box can have.

a.) Draw several diagrams to illustrate the situation, some short boxes with large bases adn some tall boxes with small bases. Find the volumes of several such boxes. Does it appear that there is a maximum volume? If so, estimate it.

I didn't do this. I'm lazy. I'm sure the grader will see my diagrams and right ending answer and be mesmorized by my awesomeness and wont even notice that I didn't do this shit.

b.) Draw a diagram illustrating the general situation. Introduce notation and label the diagram with your symbols.

c.) Write an expression for the volume.

I think I stopped labeling at this point too. :\

d.) Use the given information to write an equation that relates the variables.

e.) Use part (d) to write the volume as a function of one variable.

f.) Finish solving the problem and compare the answer with your estimate in part (a).

Oh shit....

EDIT: .... only to be annihilated by problem 14 ;____;

If I were a teacher I wouldn't ba able to make anything out of this solution good thing i'm not a teacher then.

and I haven't done this kind of math in a while

I always learned to explain my equation otherwise I get points deducted but i gues

I'm lazy.

v=x(3-(2x)^2)
v=x(4x^2-12x+9)
v=4x^3-12x^2+9x

Find Maximum of v where 0<x<1.5.

Accomplishment of the day so far: I'm out of bed.

Looks like you didn't get much more accomplished than that either.

This is one elementary problem of derivatives.. Too easy.

All well and good, but that's not really YOUR accomplishment, is it?

I got awards for the following:

-Honorable Mention in Science Fair (CS category)

-Top 1% on Financial Literacy Test for Personal Finance (only 16, test was nation wide, average score: 52%, my score: 94%)

-Top 5% on PSAT

-Got 92.6 A on Geometry Test I didn't study for (my teacher is a PhD in Math, so even if it would be a normally easy course my teacher is good at making it harder than it needs to be.)

-My web design group for school really pleased our clients (non-profit) with our site!!!!!!!!!

-My Idiot Programming Teacher Turned to Me To Double Check His Work!!!!!! (and then admitted he just learned the new material)!!!!!!!!!!!!!!!!!!!

Sorry for the rudeness but I'm still in high school.

by the way, what's 'calc 1' ???? I guess you are talking about some kind of semester... right?
