Prove graphically and algebraically that a clockwise rotation of 270° about the origin has an equivalent counterclockwise rotation. In your final answer, name the equivalent counterclockwise rotation and show all of your
work. On your graph, label the following:
1 parallelogram PARK and the coordinates of all four of its vertices
2 parallelogram PARK and the coordinates of all four of its vertices
3. center of rotation and its coordinate
4. the invisible circle of rotation, its radius and the length of the radius
5. use arrows to show the clockwise movement of the parallelogram

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
