🚀 Trigonometry in Space Exploration

Celestial navigation and orbital mechanics depend on advanced trigonometric calculations.

Key Applications

Small Angle Formula: θ ≈ 206265·D/d
Where:
θ = angular size (arcseconds)
D = actual diameter
d = distance

Mars Approach

Calculating apparent size at closest approach:
D = 6,779km, d = 54.6M km
θ ≈ 206265×6779/54,600,000 ≈ 25.6"
