New Math problem with 100% less 12 year old.

Damn this proves I suck at math. Thank god I found a way to make good money without going through those courses.

that would leave you with v/1/3*1/pi*r^2 the 1/3 is under the v not the 3


fresh gear must be 11, i know we learned fractions before that.

ahh man, i was thinking about it a bit later and realized where i made that mistake.

hey, give me a break, i just came back from summer break!

and i did it in my head, instead of on paper, etc

wait till my AP physics calculus class starts to move along and i'll remember all that was lost.

(1) –[p(x)y’]’ + q(x)y = λy

-satisfy boundary conditions :

A1y (a) + B1y’ (a) = 0

A2y (b) + B2y’ (b) = 0

t/f?

Wait, you just wanted to convert it to rectangular. So then, why were you asking what to put down for r? Couldn't you have just drawn a right triangle and then used simple trig?

Like this:

Not sure if you realize it or not, but your way isn't any different, it's pretty much how the formulas (x=rcos(theta) & y=...) are derived. The only difference is, your method takes a little bit longer.
