i only have the finaly answer (pi) but i don'tknow did they it
anonymous

what level is this?
walters
  • walters
second
anonymous
  • anonymous
second what?
walters
  • walters
ok maybe i don't understand u which level are u refering to?
anonymous
  • anonymous
which grade?
walters
  • walters
advanced calculus
anonymous
  • anonymous
past vector calculus?
walters
  • walters
i did pure calculus now is the second level of it (which is advanced calculus)
anonymous

have you done double and triple integrals? i only ask because i think i saw something similar a couple days ago.
walters
  • walters
i am not sure whether this is possible The substitution of x=-y yields |dw:1360491262699:dw| NB:not sure

@phi pls help
hartnn
  • hartnn
do you know a standard integral... \(\int \limits_a^b f(x)dx =\int \limits_a^b f(a+b-x)dx \)
hartnn
  • hartnn
*standard property.
walters
  • walters
no
hartnn
  • hartnn
ok, then do you want to use this (1 method) or continue with what u did (another method) of putting x=-y...
walters
  • walters
any method u know u can use it i'll try to catch up
hartnn
  • hartnn
ok, i'll tell u both, first using your substitution x=-y, |dw:1360492675542:dw| |dw:1360492681874:dw| understood till here ?
walters
  • walters
ok this means i will have |dw:1360492779070:dw| @hartnn can u pls teach me/explain standard property
hartnn
  • hartnn
yes, you got it correct using your method, now the standard property... let I = integral ..... -------->(1) now using that property, first tell what is a+b-x =.... ?
walters
  • walters
pi-pi-x=-x
hartnn
  • hartnn
yes, so, because of that property, |dw:1360493289196:dw| add 1 and 2 what u get ?
walters
  • walters
|dw:1360493238315:dw|
walters
  • walters
from -pi to pi
hartnn
  • hartnn
umm...not actually.... |dw:1360493484296:dw| |dw:1360493501827:dw| s = sin x
hartnn
  • hartnn
|dw:1360493565788:dw|
hartnn
  • hartnn
got that ^ ?
walters
  • walters
wow i see now so tell me how wil i know that i must use standart property
hartnn
  • hartnn
thats trial and error, i first thought of substitution, then recalled different properties, then this property was found to be useful...wih enough practice, this procedure becomes easy and fast...
hartnn
  • hartnn
also you must know all the properties beforehand ...
walters
  • walters
ok thnx
hartnn
  • hartnn
welcome ^_^
