Use the right-endpоint аpprоximаtiоn RnR_n to find аn approximation to the area under the curve f(x)=4xf(x)=4x on the interval [0,3][0,3], and then find the exact area as the limit of the Riemann sum RnR_n as n→∞nrightarrow infty.The following formulae may be useful:∑i=1n1=1+1+1+…+1=nsum_{i=1}^{n} 1 = 1+ 1 + 1+ dots + 1 = n∑i=1ni=1+2+3+…+n=n(n+1)2sum_{i=1}^{n} i = 1+ 2 + 3+ dots + n = dfrac{n(n+1)}{2}∑i=1ni2=12+22+32+…+n2=n(n+1)(2n+1)6sum_{i=1}^{n} i^2 = 1^2+2^2+3^2+dots+n^2 = dfrac{n(n+1)(2n+1)}{6}
