"From Stargazers to Starships" tries to be selfcontained,
even in the mathematics it uses. The sections below are meant to
refresh your memory about some basic ideas in algebra and trigonometry.
Even if this material is completely new to you, with enough motivation and persistence you should be able to understand it. Care was taken to remove any potential stumbling blocks.
And if algebra and trig are old hat to you, rest assured that you will still find here some unexpected goodies.
Here is what is covered:
Elements of algebra
(M1) Basic ideas
(M2) How it all started
(M3) Formulas
(M4) Identities
(M5) Deriving Approximate Results
(M6) The Theorem of Pythagoras
Elements of trigonometry
(M7) What is it good for?
(M8) How to tell sines from cosines
(M9) Deriving sines and cosines
(M10) Going past 90 degrees
(M11) Deriving sin(a+b),
cos(a+b)
