Question

How do you graph `r=1+2sintheta`?

Answer 1

Here is the graph.

Explanation:

graph{1+2sinx [-10, 10, -5, 5]}

I think there is nothing to explain.

Hope it helps...

Thank you...

Answer 2

Make a table of θ and calculated r values. Plot them on graph paper or use a suitable computer program.

Explanation:

ALL graphing must start with the calculation/collection of the relevant points! After that, it is just a question of putting them into the format (Cartesian or Polar) that is most appropriate.

Maybe the problem is that not very many computer programs can do polar plots easily. One can still be constructed quickly from the table of values, which can still be generated very quickly with a spreadsheet program.
