1. The problem statement, all variables and given/known data Convert to standard form ODE system y0 = f(t, y): t^2y'' + sin(y') + 2y − 1 = 0 the goal is to reduce the equation above to be a first order ode. 2. Relevant equations 3. The attempt at a solution I tried to introduced a new variable but the sin(y') seems tricky.
