How to bring up split window to type algebraic objects when it is concealed?
I was successfully entering the equations necessary to generate a correlated bivariate Gaussian distribution in Geogebra 3D, and I had to save my work. When I came back to it the column on the right where you can type equations, vectors, curves, surfaces, etc using algebra (I believe it is called CAS) flashed for a second as the app opened, and then went away, and couldn't bring it back up. (see attached image of my screen).
I'm using Windows 10.
