Topic: Lissajous Curves - Why must Settings be Radians and not Degrees

Please see the attached and the last equation in the list x(t)=3sin (4t), y(t)=3cos (3t).
Under the Settings for the Coordinates, why must the setting be radians instead of degrees to properly display the graph?
Perhaps this relates to issues in my previous Post (I will take a look at over the weekend),

You have been very responsive, thank you very much.

Re: Lissajous Curves - Why must Settings be Radians and not Degrees

The sin and cos functions depend on the trigonometry setting. If it is radian, the argument to sin and cos are between 0 and 2pi. If it is degree, the argument is between 0 and 360. You should probably just let it stay as radian. I regret implementing support for degree as it just makes things complicated.
