Question

water draining question math!!

Answer 1

oh dude those are pain in the but

Answer 2

1. why is there pi on both sides
2. and where did 1/72 dt come from? what happened to the y?

Answer 3

the pi just carrys over from algebra.... and the 1/72 and y come from when you plug it in and do the math over as shown... lol im not sure whats the problem

Answer 4

@elctronicz:
yes i know this is such a pain question =( and im so confused and frustrated since i dont seem to understand even i am looking at the text !

Answer 5

i dont understand what they are doing.. that is the problem

Answer 6

LOL wut the what math are u in? i dont think i learn this yet LOLLLL

Answer 7

its from differential equation/linear algebra text book =(

Answer 8

um they just took the integral.... you done calculus right?

Answer 9

@Goten77
um.. yes if i knew what the problem is i wouldnt be asking here =/ .. and that really doesnt help at all.... if your asking me if i done calculus..

Answer 10

well cause if you havent dont calculus then i can know why you wouldnt understand this....

Answer 11

@Goten77
im more of the visual person i have to see the steps, the way your telling me is no different from what my professor is saying ...

Answer 12

i havent explained anything yet.. im just asking "have you taken calculus yet" if not then explaining this would be extremely hard and if so then I can maybe show you how it works out....

Answer 13

@Goten77
yes i've taken calculus =(

Answer 14

k so theres pi on both sides cause
pi is just a constant *number* and while its doing dy/dt finding the derivate and substituting things the pi basically just sits there unless you were to take a different approach to distribute it *not a good idea*

Answer 15

ok i got that so basically just a constant.

Answer 16

wait is this a physics problem? ....... i keep thinking g being gravity should be 9.8...... but its 32 so that kinda is annoying but whatever

Answer 17

oh its meter to feet conversion.... XD no wonder its so estimated

Answer 18

i have no idea... lol

Answer 19

You know the disk method?

Answer 20

what do i do now? i did it get 1/72dt?

Answer 21

how*

Answer 22

disher/washer method doenst really mean antyhing at this level in calculus.... but like its showing the work kinda ina weird way *outta place if u must say*
im sure youll get this
that 1/72 is another constant
