Hints: The sun's rays is always perpendicular to the earth's surface at some point. That point lies on a "latitude" value. That latitude value is between the Tropic of Cancer and the Tropic of Capricorn. The earth's orbit is assumed circular (revolution). The tilt and revolution causes this "latitude" value to vary.
Mathematics is technically not a science subject, however it is a tool (just like English) that is needed by science to complete science, or else science would not be what it is now. Good luck figuring out the maths.

Reason: Highlight hint
It's not easy to become a better person, but its good.
It's easy however to loose yourself in worldly riches, and evil.
It's a choice to be better. Better is relative, and exist for all us parasites.
