I have the following differential equation
sol = NDSolve[{y'[t] == y[t] - 2*Exp[-t], y[0] == 1}, y, {t, 0, 10}] Plot[y[t] /. sol, {t, 0, 4}, AxesLabel -> {"Time--->", "y(t)--->"}]
how to control the step size of NDSolve
Click on NDSolve documentation
Click on >Details and Options
Scroll down to find MaxStepSize
Insert ,MaxStepSize->10^-9 inside the closing ] of your NDSolve
Evaluate
(Use this method for most questions to see if the answer is in the documentation)
Thank you
