Mollweide’s Formula Another form of Mollweide’s Formula is
Derive it.
Venus The distance from the Sun to Earth is approximately 149,600,000 km. The distance from the Sun to Venus is approximately 108,200,000 km. The elongation angle is the angle formed between the line of sight from Earth to the Sun and the line of sight from Earth to Venus. Suppose that the elongation angle for Venus is 10°. Use this information
to find the possible distances between Earth and Venus.
If is an acute angle, solve the equation.
