Circle.tangent_at

Circle.tangent_at(t, world=True)

Construct a tangent on the circle at a specific parameter.

Parameters:

tfloat

The parameter of the tangent vector. The parameter is expected to be normalized, and will be mapped to the corresponding angle in the interval [0, 2 * pi].

worldbool, optional

If True, the tangent is returned in world coordinates.

Returns:

compas.geometry.Vector

The tangent on the circle at the specified parameter.
