Introduction
The purpose of this investigation, The Unit Circle, is to understand the values and relationships between sine, cosine, tangent, secant, cosecant, and cotangent. The investigation requires two graphs, both labeled with each of the fundamental identities. After these graphs are completed, there are a series of questions that require the knowledge of not only the values of the fundamental identities, but also there placements on graphs.
The Academic Skills and Objectives That I Used Were:
- Verbal descriptions into mathematical expressions
- Define using the unit circle, graph and use all trigonometric functions of any angle. Convert between radian and degree measure. Calculate arc length, and area of a sector in a given circle.
- Prove trigonometric identities and derive some of the basic ones. Know the fundamental identities.
- Know basic trigonometric identities for sine cosine and tangent ( Fundamental, sum and difference, co functions, double and half angle formulas)
Justification
I put The Unit Circle project on my portfolio because it shows the skills I learned about the fundamental identities. Drawing these graphs and answering the questions required knowing the placements of the fundamental identities on the unit circle as well as what dictates there placements.
