So I'm tutoring this girl in Calculus....

[polarmystery]

If any male can focus on mathematics with a 36DD next to them... well, I'm not sure male would be the appropriate term anymore. Maybe not even alive.

seconded.

fail

 

[DrPizza]

Calc is easy, so are differential equations.
Pics?

That depends on the teacher. One of today's problems was to find the arclength of y=x² from x=0 to x=1. If calculus is "easy", then you'll have no problem doing that problem by hand, right?

Let me find my book, look up how to do an arclength problem, and I'll get back to you on that.

Now you've got me curious...

Oh right, it's that formula. My teacher just had us write the formula out, plug in the pieces... and never do the integration.

Thread may as well have just ended there.

Arclength part is easy. it is
integral of sqrt (1^2+(2x)^2) from 0 to 1

2x came from deriving x^2

Difficult part is integrating that messy square root. Need some nasty trig substitutions there.

Using a calculator, answer is ~1.48

Am I right Dr. Pizza?

Yeah, too bad for lazy teachers.

I don't get the fail. Why does everything need to be about the females?

I don't remember this, but I believe this is correct. It's probably not the easiest way to do it, but you don't have to search for trig substitutions. Pardon me because it's been like 4 years since I've taken any calculus.

Algebra reaches the form in first line. And the limit is 0 to 45 degrees, since arctan(1/1) = 45 degrees. You can know look up this integral in your favorite handbook.

Using the calculator to arrive at that solution isn't doing calculus. Nasty trig substitutions? Nahhh, the trig substitution is pretty simple. Replace x with 1/2 tan theta. If I recall correctly off the top of my head, you wind up with the integral of secant^3.

And, that's another fun one to do by hand.

Big to switching to polar coordinates. My students haven't gotten to working with polar coordinates yet; it's just calc I. But a to using a handbook. Where's the challenge in that??

 

[Macamus Prime]

Math?!

Are you some sort of communist?!?!

Yeah my expression above is missing a term. I did not account for the variation in the radial direction, in which case instead of

It should be the norm of the polar 2-vector

It's not as easy as I had thought.

 

[Fayd]

yeah... my final in calc 2...is.. tonight...

 

[bigrash]

i would but the pages are stuck together from after the last time i tutored a girl in calculus.

Spilled soda again while tutoring?

 

[MotF Bane]

Spilled soda again while tutoring?

--> Beefpile (~mbeefpile@cloaked.wi.rr.com) has joined #themacmind
<anamexis> and it exploded
<anamexis> ALMOST all over my keyboard
<anamexis> but I got it away just in time
<-- Beefpile has quit (sick fuckers)

I misread the title as "So I'm torturing this girl in Calculus"...must be the dyslexia.

The three girls (my entire calculus class) would agree that I'm torturing them in calculus.

 

[zinfamous]

lol. I love Arcadio threads.

 

[Locut0s]

i have a integral problem for you and your student.

&#8747;f(36 DD cup)dt

dt? This should be a volume or surface area integral. What is time doing in there?

whatever, I took calculus over 10 years ago. or maybe his student is an a cup and needs time to grow into a DD

giggity?

 

[brainhulk]

Is her teaching her calculus by any chance? You don't have to worry about a thing cause he's gay.

no wonder

You forgot about the jiggle.
