Greetings, I’m a relatively new Julia user and have encountered a problem. I’m a bit embarrassed to post it here, since it seems sure to be something really obvious. A brief statement of the problem is as follows. I am trying to solve a second-order differential equation which depends on an external…

This equation has an analytical solution [image] u''[t] = -u[t] + 0.8*Sin[10*t], u[0] = 0.1, u'[0]=0.0 - Wolfram|Alpha Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. …
