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.

His sheet does not work for Mathcad 15 with muPad

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 ?)
