Sketch the graph of a polar equation

  1. Sep 1, 2008 #1
    1. The problem statement, all variables and given/known data

    r = 1 - 3cos(t)

    2. Relevant equations

    I made a table from 0 to pi, plugging the values of theta into r = ...


    3. The attempt at a solution

    After doing the table, when i go to plot points, at 2pi/3 through 5pi/6 i am having to plot points that really stretch the graph and it goes beyond (on the y axis) what my graphing software is showing. The software shows the graph being below around 2 all the way around. What is the deal here. for instance at 3pi/4 my r equals 3.12 so this makes me extend further than i should be. what am i missing here


    HAHA OK JUST REALIZED I AM IN RADIAN MODE ON THE TI 83 NOT DEGREE DUHHHHHH OK SORRY
