In x = a cos t, y = b sin t, the parameter t is called the:
AMean anomaly
BEccentric anomaly
CPolar angle
DTrue anomaly
Answer & Solution
Correct answer: B. Eccentric anomaly
In the standard parametric form of the ellipse, t is known in astronomy as the eccentric anomaly and is not the polar angle of the point.
