Best ResponseYou've already chosen the best response.0\[\int\limits_{0}^{1} \sin(y)(ee^{y^{1/3} })dy\] is the integral. I can plug it into wolfram alpha and get a value, but I would like to know what steps get me there>

Best ResponseYou've already chosen the best response.0Wow. That's an interesting integral. I would suggest distributing the sine function across and take the integral sepearately. e is constant so you can just factor that out. For the second integral, it gets a bit difficult. You could try and work with integration by parts twice.

Best ResponseYou've already chosen the best response.0Except that the product of siny and e^y^1/3 is elliptic. Neither of those will differentiate to zero.

Best ResponseYou've already chosen the best response.0Heh, I have a whole homework sheet of these iterated integrals that the inner integral isnt bad, but the insides are just impossible. WA wont even give steps, just values when I include the bounds.. Arg

Best ResponseYou've already chosen the best response.0have you tried considering y^(1/3) as u ?

Best ResponseYou've already chosen the best response.0I don't think you can use usub, since you don't have a du to substitute. But, I think since the integral is from 0<y<1 so it might be easier to just use the bounds given to evaluate. In theory, I think you can use series to solve this.

Best ResponseYou've already chosen the best response.0Not series to solve the whole integral! Omg.

Best ResponseYou've already chosen the best response.0unless u want to use integration by parts and the Jacobin and polar coordinate,

Best ResponseYou've already chosen the best response.0Well, depending on the course this is being taught in, which is probably a Calc BC (II) course, I would suggest parts. However, if this was for ODE, then I might suggest using poolar coordinates or series expansion.
