int (0)^(1) xe^(x^(2))dx is equal to...

` int _(0)^(1) xe^(x^(2))dx` is equal to

A

`(1)/(2)(e+1)`

B

`e-1`

C

`(1)/(2)(e-1)`

D

`(e^(2))/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Let ` I = int _(0)^(1) xe^(x^(2)) dx`
Put ` x^(2) = t rArr 2x = (dt)/(dx)`
` rArr dx = (dt)/(2x)`
` :. l = int _(0)^(1) xe^(1) (dt)/(2x) = 1/2 int _(0)^(1) e^(t) dt `
` = 1/2 [ e^(t)] _(0)^(1) = 1/2 [e^(1) - e^(0) ] = 1/2 [ e-1 ] `
