Hy, I'm a french student and I need to solve a beautyful equation, this could be an exemple :

g(t)*sin(f(t)+B(t))+h(t)*cos(B(t))+d²(B(t))/dt²=0

g, h and f are known and I need B.
I know that I won't be able to find an analytic solution, but I would like to use a numeric solution. I'm a beginner in matlab, I realy need help.
Thanks for reading my message.

Okay, then you should read through the help and/or documentation for the
ODE45 function.

Type "help ode45" and/or "doc ode45" (each without quotes) at the command
prompt.
