Solving for (\theta_3) and (\theta_4) (the coupler and follower angles) requires solving a , often handled via the Freudenstein equation:

Breaking into (x) and (y) components for a given crank angle (\theta_2): 4 bar link calculator

Differentiating the loop equations yields angular velocities using the known input angular velocity. Solving for (\theta_3) and (\theta_4) (the coupler and

Given link lengths and crank angle, output the angles of the coupler and follower, plus the coupler point position. plus the coupler point position.
