1.	If y=[x]4+{x}+{x}[x]−3, then dydx at x=π is(Where [⋅] denotes the greatest integer function and {⋅} denotes the fractional part function)
Answer» If $y = [x]^{4 + {x}} + {x}^{[x] - 3},$ then $\frac{d y}{d x}$ at $x = π$ is $($ Where $[\cdot]$ denotes the greatest integer function and ${\cdot}$ denotes the fractional part function $)$
