Could you please tell me how to plot r=2cos theta ? Please show me the step of plotting this graph. Thanking in advance.
Then calculate the r value for each . They are
What do you do with negative r values? Well, you make the r value positive and then add (or subtract) rad to the angle.
So we wish to plot the set of points:
Then you plot the points on polar coordinate graph paper and sketch in a smooth curve between the points. I get the graph below.
