Find the value of int(0)^(1)x(1-x)^(n)dx...

Find the value of `int_(0)^(1)x(1-x)^(n)dx`.

Text Solution

Verified by Experts

`int_(0)^(1)x(1-x)^(n)dx`
`=int_(0)^(1)(1-x).{1-(1-x)}^(n)dx`
`=int_(0)^(1)(1-x).x^(n)dx`
`=int_(0)^(1)(x^(n)-x^(n+1))dx`
`=[(x^(n+1))/(n+1)-(x^(n+2))/(n+2)]_(0)^(1)`
`=(1)/(n+1)-(1)/(n+2)=(1)/((n+1)(n+2))`
