The vaue of `underset(-1)overset(2)int (|x|)/(x)dx` is

Let [t] denote the greatest integer le t. Then the value of 8 underset(-1/2)overset(1)int [2x]+|x| dx is ____________

underset(1)overset(e)int (e^(x))/(x) (1 + x log x)dx

Estimate the value of underset(0)overset(1)e^(x^(2))dx by using underset(0)overset(1)e^(x)dx .

underset1overset2int 3x^2dx =???

The value of underset((-pi)/(2))overset((pi)/(2))(int) (1)/(1 + e^(sin x)) dx is :

If f(x)={{:(x,xlt1),(x-1,xge1):} , then underset(0)overset(2)intx^(2)f(x) dx is equal to :

" If " Delta (x)=|underset(9" "x" "-7)underset(6" "4x" "3)(1" "x^(2)" "x^(2))| then find the value of overset(1)underset(0)(int)Delta (x) dx without expanding Delta (x) .
