Find the value of : `int_0^(10)e^(2x-[2x])d(x-[x])w h e r e[dot]` denotes the greatest integer function).

Answer

`10(e-1)`

Explanation

`int_(0)^(10)e^(2x-{2x})d(x-[x])`
`=int_(0)^(10)e^([2x])dx`
`=20 int_(0)^(1//2)e^({2x})dx` ( `{2x}` has period `1//2`)
`=20 int_(0)^(1//2) e^(2x)dx`, [for `x epsilon(0,1//2),{2x}=2x`]
`=10(e^(2x))_(0)^(1//2)`
`=10(e-1)`
