passport to advanced math: trigonometry
summary
the content provides an in-depth exploration of the six trigonometric functions, emphasizing the importance of understanding their relationships and applications, particularly in the context of the sat exam.
- introduction to the six trigonometric functions derived from the sohcahtoa triangle, including sine, cosine, tangent, cotangent, secant, and cosecant.
- explanation of the geometric origins of cotangent, secant, and cosecant, and their relationships to sine and cosine.
- discussion on the reciprocal nature of the trigonometric functions and the significance of memorizing these relationships for the sat exam.
- overview of the pythagorean identities and their derivations, highlighting their utility in solving problems and their critical role in calculus.
- practical application through a practice problem, demonstrating how to apply trigonometric identities and the pythagorean theorem to solve for unknown variables.
