Eccentric anomaly hypotenuse: Thus, the radius (distance from the focus to point "P") is related to the eccentric anomaly by the formula With this result the eccentric anomaly can be determined from the true anomaly as shown next. The "true anomaly" is the angle labeled "f" in the figure, located at the focus of the ellipse. In the calculations below, it is referred as "θ". The true anomaly and the eccentric anomaly are related as follows. Using the formula for "r" above, the sine and cosine of "E" are found in terms of "θ": Hence, Angle "E" is therefore the adjacent angle
