If we let f(x) = x^2, then we can expand d/dt[f] as df/dt = df/dx * dx/dt. Looking at the final expression, df/dx * dx/dt, we can verify that the equality indeed holds true because the dx terms cancel (leaving us with the original df/dt).From here, it's a matter of using power rule to find df/dx: df/dx = d/dx[f] = …
