WebNov 28, 2024 · Next we need to also define theta-dot and theta-double dot (the first and second derivative of theta with respect to time). We already have defined theta, so I can define theta dot as the derivative of theta with respect to time. I can do something similar with theta double dot. Yes, sympy has a differential function called “diff”. WebThe theta indicates the angle, a single dot above theta indicates first derivative of the angle, which would give the angular velocity, a double dot (umlaut), indicates second derivative of the angle, which would give angular acceleration. Just to add to the above answer, the dot or double dot always refers to the derivative with respect to ...
