1. The problem statement, all variables and given/known data Solve d2y/dt2 = dx/dt2, if x = 0 and dx/dt = 1 when t = 0 2. Relevant equations 3. The attempt at a solution d2y = dx I'm not exactly sure what to do here the fact that dt2 is under the denominator for both fractions is confusing memaybe its a typo? should it be d2y/dx2 = dx/dt?
