II am working on some mechanical problems.
basically trying to take symbolic derivative of kinematic coefficients for the purpose of checking my hand calculations..
so here is the position scaler ; r2 cos(th2) - r3 * cos(th3) = 0
taking derivative with respect to th2 (theta2) , Vx = -r2 *sin(th2) + r3 *sin(th3) * d(th3)/d(th2) - cos(th3)*d(r3)/d(th2) = 0
and differentiate again for acceleration with respect to th2
Could you please explain on how this can be achieved using matlab?
