Three-dimensional objects are projected onto screens with finite dimensions, it often limits the field of view
(fov), or the angle the scene represents. this limiting effect can vary based on the size of the screen and position
of the observer.
a. sketch a diagram that could be used to calculate a viewer’s field of view theta in relation to the horizontal width
of the screen w and the distance the viewer is from the screen
b. assume that a person is sitting directly in front of a television screen whose width is 48 inches at a distance
of 8 feet from the screen. use your diagram and right-triangle trigonometry to find the viewer’s horizontal
field of view theta.
c. how far would a viewer need to be from the middle of a computer screen with a width of 15 inches to produce
the same field of view as the person in front of the television?
d. write a general statement about the relationship between screen size and field of view.

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

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?
