**1. Homework Statement**

I don't understand why when we derive the velocity equation of motion in polar coordinates we start with position equal to R times R hat and not (theta times theta hat + R times R hat).

**2. Homework Equations**

none really..

**3. The Attempt at a Solution**

Is there an assumption I'm missing? or is it simply differentiating linear and angular velocity that is messing me up?
