POLAR COORDINATES Evaluating Polar Functions (Page 6 of 7)

Now let's use the table to evaluate the function r1 for θ-values spaced 10° apart, starting at θ = -30. Return to the table setup screen. TblStart is the value of θ that you would like the table to begin at, and ΔTbl is the spacing between θ-values. We also want to change the independent variable setting to Auto.
