Find an Approximation for the Integral $\iint _ { R } \left( 4 x - 5 y ^ { 2 } \right) d A$

question 9

Short Answer

Find an approximation for the integral. $\iint _ { R } \left( 4 x - 5 y ^ { 2 } \right) d A$ Use a double Riemann sum with $m = n = 2$ and the sample point in the upper right corner to
approximate the double integral, where $R = \{ ( x , y ) \mid 0 \leq x \leq 8,0 \leq y \leq 4 \}$ .
