Trigonometry
Section 1 Chapter 1
Degree and Radian measure
Trigonometry will involve an in depth study of angles and how they relate with the math concepts we have been taught and will learn
Terminal side
Estimate the angle measure
Initial side
For our purposes, we will put angles in standard postion
We may have positive or negative angles
Radian Measure
Arc length (s) = radius (r) x Angle in Radians (θ)
Benchmark Angles
Coterminal Angles
Supplementary and Complimentary Angles
Conversion between degrees and radian measures
Radians to Degrees
Degrees to Radians
In Radians, what is one­
eight of a revolution counterclockwise around the coordinate plane
