if u want polar u can do upper triangle in polar subtract lower triangle in polar same method

- dan815

or all of that can be set up in polar 1 shot

triangles in polar are fun :D

Why would you want to do this in polar? Seems like a pretty straightforward problem as written, am I missing something?

- anonymous

It NEEDS to be in polar, unfortunately :( That's what makes it tricky!

- dan815

lol

- whpalmer4

It needs to be in polar because the problem statement says so?

- anonymous

Yes

- anonymous

I know it sounds stupid but it does

- whpalmer4

Okay, you'll forgive me for not understanding that, as it isn't actually stated above :-)

- anonymous

What do you mean? Yeah it is

- whpalmer4

sorry, it does, just not where I had the window scrolled, sigh.

- anonymous

lol xD

I just saw "FutureMathProfessor: The trickiest double integral question" on the left side of the screen, "- SOLVE IN POLAR!" was below the fold, so to speak.

gimme medal i finished it for u... yeww butttboy

- dan815

:D

Well how do I find the 2nd limit?

- dan815

the intersection between line x=2 and y =sqrt3 x

- anonymous

so 2sqrt(3)?

- dan815

tan theta = sqrt3 *2 / 2

- dan815

theta =?

- anonymous

pi/3

- dan815

there u go@!! :)|

- anonymous

I was right??

- anonymous

LOLOL that was a pure 1000000000000000000000000000000% guess

- dan815

i dunno lol i just figure u did thr work bahnahah

- primeralph

kids.

Were people supposed to memorize all points on the Unit Circle in trig class? I never did

- dan815

me too xD

- anonymous

If someone told me what's x when cosx is sqrt(2)/2 I wouldn't know

- anonymous

When cosx is sqrt(2)/1 does that mean the angle is pi/4?

- dan815

|dw:1370929915787:dw|

- dan815

pi/3 u were right

- anonymous

OMFG THAT'S THE 30 60 90 FORMULA!

- anonymous

L00000000000000000000000000000000000000000000000L

I'm learning so much tonight

- dan815

YESS GOLD MEDAL

- anonymous

Is that what all of this is based off of? the 454590 and 306090 formulas?

- dan815

yeah future

- anonymous

lmfao..

- anonymous

so tan of 5pi/6 is -1/sqrt(3?)?

- dan815

root3/-1 not -1 over

- anonymous

How would that side be sqrt(3) if the angle is only 30 degrees?

- dan815

oh nvm u are right

- dan815

i forgot that is 30 degrees

- dan815
