Polar Graphing restricting r>=0 #2162

Open Steven-Wells opened 5 months ago

Steven-Wells commented 5 months ago

It would be great if when sketching polar curves you could restrict the range of values of r so that r is greater than or equal to 0. The specification we use for our course specifies that students shouldn't draw negative values for r so we are unable to use the calculator for sketching polar curves.

I would like to second this request as it's also something we've come across teaching Y2 Further maths A-Level (perhaps this is the same course as you are teaching).

Thanks, James

It is indeed

ukr-reader commented 5 months ago

A hack in the interim is to plot r=(sqrt(f(theta))^2

But yes, another vote from me for having the option to restrict polar plots to r>=0.

Hello, Thank you for this suggestion. An issue is already opened in our internal repo on this topic. It is yet to be prioritized, I will let you know once we develop the feature.
