a cosine function with no phase shift whose x-coefficient is 1
a sine function whose graph shows 2 cycles from - 41 radians to 0
a sine function whose graph shows 2 cycles from 0 to 21 radians
a cosine function whose graph shows 4 cycles from 0 to 41 radians
a cosine function whose graph shows 1 cycle from 37 radians to 57 radians

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
