Use a numerical solution with either "root" or a solve block, as we had it here already so often

Luc is using Mathcad 11 with Maple as symbolics engine.

Here is a workaround.

After all we don't need the exact derivative of the floor-expression (step function) which is all zero but with Dirac spikes at the odd multiples of pi. So substituting it with a constant does the job in MC15

Plotting the local maximum-points of the 'red' ?

Adding -2*pi to the one old root ( the old 'red' point ) to get another new root ( another new 'red' point (backward to the left) )  is correct or not ? ( yes or no for periodic property ?)

no, its not periodic
