The tangent function is discontinuous in PI/2 + n*PI, so you should break it to pieces at those intervals. No, you don't need to uninstall numpy, you just have to import math as a module.

We extend the finite type condition to graph-directed iterated function systems with overlaps. Under this condition, we describe algorithms to compute the box dimension and Hausdorff dimension of the ...

We propose applying the reaction-diffusion equation on a graph to the function approximation for reinforcement learning. which realizes adaptive resolution according to the complexity of the ...
