Document Summary
Point values in boxes : 5 calculate the uid force of a plate in the shape of the region shown in the gure below. The surface of the mystery uid of density is at y = 1: 2 find parametric equations, x(t) and y(t), for the line segment from (3, 2) to (5, 2). Include the domain of t: 2 find parametric equations, x(t) and y(t), for the circle with center (1, 2) and radius 3. Include the domain of t: 1 we can change the speed" of a parametric curve by scaling the parameter. For example, replacing t with 2t will increase the speed by a factor of two, i. e. the curve will be traced out twice as fast. We can change the direction a curve travels by similarly altering the parameter. A cyloid generated by a circle of radius 1 has a parameterization given by.
