    Tries to convert the time from periapsis passage to hyperbolic anomaly. The value returned is signed and monotonic.
    
    Parameters:
    
    timeFromPeriapsis - The time from periapsis passage (time).
    
    radiusOfPeriapsis - The radius of periapsis (distance).
    
    eccentricity - The eccentricity of the orbit.
    
    gravitationalParameter - The gravitational parameter (distance cubed per time squared).
    
    hyperbolicAnomaly - On input, an array with one element. On return, the array is populated with the hyperbolic anomaly (radians).
    
    Returns:
    
    false if eccentricity is less than or equal to one (indicating that the orbit is not hyperbolic) or radiusOfPeriapsis or gravitationalParameter is negative or zero; otherwise true.

```
    Tries to calculate the time of flight between two true anomalies.
    The sign of the true anomaly indicates whether the position in orbit was measured before or after crossing periapsis.
    
    Parameters:
    
    initialTrueAnomaly - The initial true anomaly (radians).
    
    finalTrueAnomaly - The final true anomaly (radians).
    
    radiusOfPeriapsis - The radius of periapsis (distance).
    
    eccentricity - The eccentricity of the orbit.
    
    gravitationalParameter - The gravitational parameter (distance cubed per time squared).
    
    timeOfFlight - On input, an array with one element. On return, the array is populated with the time of flight (time).
    
    Returns:
    
    true if the time of flight could be calculated with the given elements; otherwise false.
