To apply Lagrange’s equations, we determine expressions for the kinetic energy and the potential as the. system moves in angular displacement through the independent angles θ1 and θ2. From the geometry we. have. x1 = h1 sin θ1. y1 = −h1 cos θ1. x2 = h1 sin θ1 + h2 sin θ2. y2 = −h1 cos θ1 − h2 cos θ2.
