Let R denote the region enclosed by the x-axis, the line x = 1, and the curve y = x. Use the method of cylindrical shells to calculate the volume of the solid obtained by rotating the region R about the line x = 1. 12. Find Z √ x3 dx . x2 + 1 13. An animal population is increasin at a rate of 200 + 50t per year ( where t is measured in years). By how much does the animal population increase between the fourth and tenth years ? 14. Find the interval on which the curve Z y= 0 x 1 dt 1 + t + t2 is concave upward . 15. The velocity function ( in meters per second ) is given for a particle moving on a line as follows v(t) = t2 − 2t − 8, 1≤t≤6 Find (a) the displacemenet and (b) the distrance traveled by the particle during the given time interval.
