For the function given below, nd a formula for the Riemann sum obtained by dividing the interval [0,5] into n equal subintervals and using the righthand endpoint for each ck. Then take a limit ofthis sum as n P on to calculate the area under the curve over [0.5]. t[x)=x2+5 ...; Write a formula for a Riemann sum for the function fix} =x2 + 5 over the interval [11.5]. 3": El (Type an expression using n as the variable.)
