Compute the Riemann sum $43 to estimate the double integral of f(x, y) = 9xy over R = [1, 5] x [1, 4]. Use the regular partition and upper-right vertices of the sub-rectangles as sample points. (Give your answer as a whole or exact number.)Evaluate the iterated integral. x'sin(y) dy dx (Use symbolic notation and fractions where needed.) x'sin(y) dy dx = 10.16666 0 IncorrectEvaluate the iterated integral.
