Best ResponseYou've already chosen the best response.0For definite integrals, the purpose is to find area under a curve. Indefinite integrals are handy for finding a function, given the rate of change of that function. idk if this is what you want...

Best ResponseYou've already chosen the best response.0Yaar @hartnn Is mai koi odd or even ka scene bhi hota hai na ?

hartnn

Best ResponseYou've already chosen the best response.2generally, if the function f(x) is odd, then \(\huge \int \limits_{a}^af(x)=0 \) if the function f(x) is even \(\huge \int \limits_{a}^af(x)=2\int \limits_{0}^af(x) \)
