I = ∫∫R xydA, where R is the region in the first quadrant bounded by the lines y = x, y = 3x, and the hyperbolas xy = 1, xy = 3. Make the transformation x = u/v and y = v Bonus: If you have done a type I integration, can you give an expression for a type II (no calculation) integral and vice-versa, or can you explain why one integral is preferable over the other.
Problem 2. Sketch the region R in the first quadrant bounded by the lines y = 3x and the parabola y = 12. Compute the area of R using (a) vertical and (b) horizontal slices. Then set up integrals for the volume of the solid obtained by rotating the region R about the x-axis. Use (c) vertical and (d) horizontal slices. (35 pts, 10 mts]
(10 points) Let R be the region in the first quadrant bounded by the x and y axes and the line y = 1 – 1. Notice R is a triangle with area 1/2 (you do not need to verify this). Find the coordinate of the centroid of R. For extra credit, determine the y coordinate without calculating an integral. (Note: If we regard R as a plate, then the centroid of R can also be thought of as the...

Let R be the region in the first quadrant bounded by the x-axis and the graphs of y = in(x) and y=5-x, as shown in the figure above. a) Find the area of R. b) Region R is the base of a solid. For the solid, each cross-section perpendicular to the x-axis is a right isosceles triangle whose leg falls in the region. Write, but do not evaluate, an expression involving one or more integrals that gives the volume of the solid. c)...
