[sage-support] Re: linear transformations (by jason Grout)

This doesn't work for me at all on CoCalc; it gets stuck in an infinite loop because of the matrix A. If I move the definition of A into the body of the loop, it seems to work. Like so: @interact def linear_transformation(theta=slider(0, 2*pi, .1), r=slider(0.1, 2, .1, default=1)):
