Example 2
The declination of the sun is the path the sun takes overhead the earth throughout the year. When the sun passes
directly overhead, the declination is defined as 0°, while a positive declination angle represents a northward deviation
and a negative declination angle represents a southward deviation. Solar declination is periodic and can be roughly
estimated using the equation
8 = -23.44° ( cos
(360
(N + 10) )), where N represents a calendar date (e.g., N = 1 is January 1, and d is the
365
declination angle of the sun measured in degrees).

When will the sun trace a direct path above the equator?
