I have a TI-84 Plus calculator and I want to understand how to set the window. I have some homework problems and the first window is given as follows for the problem sketch the curve C1 with parametric equations.
these are the equations for this problem:
x(t) = cost
y(t) = sint
0<= t <=2pi
Tmin = 0, Tmax = 2pi, Xmin = -2, Xmax = 2, Ymin = -2, and Ymax = 2 .
Does the number if frount of pi set the rest of the min's and max's?
For example if the range was 0<= t <= pi/2, would I put Tmin at 0
Tmax = pi/2, Xmin = -.5, Xmax = .5, Ymin = -.5, and Ymax = .5 or does it not work this way. I have the calculator in radians and parametric modes but I am not sure I will get the correct picture if the window is not set correctly. The problems seem to be easy, just draw the graph, show the orientation with an arrow (closcwise or counterclockwise) and fill in a table for t, x(t), and y(t). Anyway if someone could explain the window to me I would be ever so greatful!!!!!!!!!!!!!!!!
