Mathematics (All Of It) - Trigonometric Functions: Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent

Oh man, what is all this sine and cosine business? What do these things even mean?! And Greek letters now? I don't know Greek! OK friend, just relax. Understanding the trig functions is as easy as pi radians. We just make some triangles and set up a few definitions. I promise it's no sweat, just watch this!
