Hi man. Thank you so much for the videos. I have two questions: 1. if you have second derivative respect to time (t), what is the syntax for that? I tried to you $$ but it does not work. 2. if you have boundary conditions are functions of time t, how can I write the function? I tried but it gave me errors. Thank you
