Best ResponseYou've already chosen the best response.0@TuringTest why do we dont change order in this one...ans, is 1/2

Best ResponseYou've already chosen the best response.1I'm sorry, I'm either really tired or confused. It seems to me that this integral can only be done by changing the bounds. Is that what you are saying @chakshu ? You are asking why we have to change the bonds?

Best ResponseYou've already chosen the best response.0m asking that why this question is not solved by changing order of integeration its just solved simply to give ans. as 1/2

Best ResponseYou've already chosen the best response.0i will repeat turing's word. in last Q, it was difficult to integrate w.r.t y after x was integrated, thats why bounds were changed. in this case, its easy to integrate without changing bounds

Best ResponseYou've already chosen the best response.1i may be totally wrong (probably am) but isn't \[\int_0^{x^2}\frac{e^y}{x}dy=\frac{e^{x^2}1}{x}\]

Best ResponseYou've already chosen the best response.0@hartnn so ur sayin since in previous questn we had difficult limts so we changed order and in this one we have easy limits so we dont??

Best ResponseYou've already chosen the best response.1then second job would be to compute \[\int_0^1\frac{e^{x^2}1}{x}dx\]

Best ResponseYou've already chosen the best response.0ohhhhhhhh my bad frnds its e^y/x sorrrrrrrrryyyyyy for that mistake

Best ResponseYou've already chosen the best response.0its not about limits, its about what u get after integrating w.r.t one of the variables, sometimes the resulting function is very difficult to integrate w.r.t other variable...

Best ResponseYou've already chosen the best response.0In general: \[\int\limits \int\limits f(x,y)dA = \int\limits_{a}^{b} \int\limits_{g_1(x)}^{g_2(x)}f(x,y)dydx \]

Best ResponseYou've already chosen the best response.0Use parentheses. e^(y/x) or (e^y)/x?
