Best ResponseYou've already chosen the best response.0have you done double and triple integrals? i only ask because i think i saw something similar a couple days ago.

Best ResponseYou've already chosen the best response.1i am not sure whether this is possible The substitution of x=y yields dw:1360491262699:dw NB:not sure

Best ResponseYou've already chosen the best response.3do you know a standard integral... \(\int \limits_a^b f(x)dx =\int \limits_a^b f(a+bx)dx \)

Best ResponseYou've already chosen the best response.3ok, then do you want to use this (1 method) or continue with what u did (another method) of putting x=y...

Best ResponseYou've already chosen the best response.1any method u know u can use it i'll try to catch up

Best ResponseYou've already chosen the best response.3ok, i'll tell u both, first using your substitution x=y, dw:1360492675542:dw dw:1360492681874:dw understood till here ?

Best ResponseYou've already chosen the best response.1ok this means i will have dw:1360492779070:dw @hartnn can u pls teach me/explain standard property

hartnn

Best ResponseYou've already chosen the best response.3yes, you got it correct using your method, now the standard property... let I = integral ..... >(1) now using that property, first tell what is a+bx =.... ?

hartnn

Best ResponseYou've already chosen the best response.3yes, so, because of that property, dw:1360493289196:dw add 1 and 2 what u get ?

Best ResponseYou've already chosen the best response.3umm...not actually.... dw:1360493484296:dw dw:1360493501827:dw s = sin x

Best ResponseYou've already chosen the best response.1wow i see now so tell me how wil i know that i must use standart property

hartnn

Best ResponseYou've already chosen the best response.3thats 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...

Best ResponseYou've already chosen the best response.3also you must know all the properties beforehand ...
