It has been a long time since I first looked at this, so thought I might ask for some help in clarifying this problem:

Is an equation of the form -->

**Velocity = (Distance) * (Trigonometric function)**a valid one in physics?

If so, what is the relationship of trigonometric functions and dimensions in physics in this case? It seems to me that the above relationship or equation would appear to be invalid if the trigonometric function value itself is dimensionless.

--> (

**L/t**) ≠

**L*** (

**Dimensionless number**) --> where:

**L**is a Dimension of length and

**t**is a dimension of time

The origin of the question comes from a proof of Hartmann's construction used to find the center of curvature of a path in kinematics.

Thank you in advance for you help.
