" 34."int_(0)^(2)[x]dx" where "[x]" is greatest integer function."

Evaluate the following integrals: int_(0)^(2)[x]dx where [x] is greatest integers function.

int_(0)^(x) dx = "……." , where [x] is greatest integer function.

int_(-2)^(2)[x^(2)]dx (where [.] greatest integer function)

If n in N , the value of int_(0)^(n) [x] dx (where [x] is the greatest integer function) is

If f = int_(0)^(20){x}[x]dx . Where [x] is greatest integer function and {x} is fractional part function. Then, f = ?

int_(0)^(3)[x]dx= . . . ., where [x] is greatest integer funcction.
