1.	If y=[x]2+2{x}[x]+100∑r=1{x+r}2100, then ∫y⋅dx=(where [.] and {.} are greatest integer function and fractional part function respectively and c is integration constant)
Answer» If $y = [x]^{2} + 2 {x} [x] + \frac{100 \sum r = 1 {x + r}^{2}}{100}$ , then $\int y \cdot d x =$ (where [.] and {.} are greatest integer function and fractional part function respectively and $c$ is integration constant)
