maybe that method isn't going to work

what if we use the property integral ( f(x) from x=a to b = f(a+bx) from x= a to b )?
 one year ago

Jonask Group TitleBest ResponseYou've already chosen the best response.1
in this case a+b=0+1 int f(1x)=f(x)

yep, am not too sure if that'll work though, but probably should work ?

According to WA, the definite integral is 0: http://www.wolframalpha.com/input/?i=integrate+%28%281x%5E7%29%5E%281%2F3%29++%281x%5E3%29%5E%281%2F7%29%29+over+%5B0%2C1%5D Maybe there's some detail we're not getting about the function itself.

Jonask Group TitleBest ResponseYou've already chosen the best response.1
interesting result maybe this property is because of the function is actually an inverse of itself i mean \[f(x)=\sqrt[3]{1x^7}\] then \[f^{1}(x)=\sqrt[7]{1x^3}\] should this mean anything
