Hello,
I'm new to Mathematica and trying to plot a parametric equation as a solution of a system of differential equations with a parameter "a". I used ParametricNDSolve and then tried using Manipulate to change the parameter "a" with a slider. Nothing shows up on the graph.
I have successfully plotted the graph using a value for "a" and getting rid of Manipulate.
Any advice would be great!
