WebI'm trying to plot a phase portrait for the differential equation. x ″ − ( 1 − x 2) x ′ + x = 0.5 cos ( 1.1 t). The primes are derivatives with respect to t. I've reduced this second order ODE to two first order ODEs of the form x 1 ′ … WebPlot [ f [x], {x, π/15 - .01, π/15 + .01}, Epilog -> { (* add vertical lines *) InfiniteLine [ {π/15 + 1/200, 0}, {0, 1}], InfiniteLine [ {π/15 - 1/200, 0}, {0, 1}] } ] This does not require you to know the plot range, nor any of the …

WebApr 13, 2024 · For plotting streamlines and their solutions, Mathematica has a dedicated command: StreamPlot. Streamlines are similar to vector lines except this command creates lines connecting the different values instead of arrows at each point. The commands for this function are: StreamPlot [ {x^2 + y, y^2 - 4 x}, {x, -3, 3}, {y, -3, 3}] WebMay 8, 2024 · Use Show to superimpose two variants (the second one with your choice of the variable bounds -- -Pi and 2Pi in the example below) of the plot: Show [Plot [Sin [x], {x, -3 Pi, 3 Pi}], Plot [Sin [x], {x, - Pi, 2 Pi}, Filling -> Axis, FillingStyle -> Yellow]] new york times for kids
