When I am taking a partial derivative of an equation with respect to theta_dot, then theta is constant, right?(adsbygoogle = window.adsbygoogle || []).push({});

What if I am taking partial derivative with respect to theta, will theta_dot be constant?

In this case, theta_dot = omega (angular velocity), but I must keep equation in terms of theta in order to find this equation of motion by Lagrangian methods.

Thanks in advanced to anyone that can help me!
