{"library":"Scipy","prompt":"Problem:\nI’m trying to solve a simple ODE to visualise the temporal response, which works well for constant input conditions using the new solve_ivp integration API in SciPy. For example:\ndef dN1_dt_simple(t, N1):\n    return -100 * N1\nsol = solve_ivp(fun=dN1_dt_simple, t_span=[0, 100e-3], y0=[N0,])\nHowever, I wonder is it possible to plot the response to a time-varying input? For instance, rather than having y0 fixed at N0, can I find the response to a simple sinusoid? Specifically, I want to add `t-sin(t) if 0 < t < 2pi else 2pi` to original y. The result I want is values of solution at time points.\nIs there a compatible way to pass time-varying input conditions into the API?\nA:\n<code>\nimport scipy.integrate\nimport numpy as np\nN0 = 1\ntime_span = [0, 10]\n</code>\nsolve this question with example variable `sol` and set `result = sol.y`\nBEGIN SOLUTION\n<code>"}
