    The two equations that you derive by integration are all that you really need for constant acceleration:

    v = v_0 + at

    x = x_0 + v_0 t + \frac{1}{2}at^2

    provided that you're willing to solve them together with two unknowns for certain problems. The other one-dimensional kinematic equations are derived by solving these two, using different pairs of unknown quantities.
