ScalarInverseTangentGetEvaluator Method (EvaluatorGroup)

Gets an evaluator that can be used to find the angle defined by the two scalar components as a Motion<double> at a given JulianDate. The first and second derivative of the angle are also provided if the two scalars can provide their derivatives.

	EvaluatorGroup group


Type: AGI.FoundationEvaluatorGroup
The group with which to associate the new evaluator. By grouping evaluators that are often evaluated at the same Julian dates, common computations can be performed only once for the entire group instead of multiple times for each evaluator.

Return Value

Type: ScalarEvaluator
An evaluator for this scalar.
ArgumentNullException Thrown when group is .
PropertyInvalidException Thrown when ScalarX or ScalarY is .
The values returned by the evaluator conform to the implementation of Atan2(Double, Double).
