The Unit Circle and Radian Measure
Transitioning from degree based measurement to the more natural unit of radians for circular motion.
Key Questions
- 1Why is radian measure considered a dimensionless unit and why is this advantageous in calculus?
- 2How does the unit circle allow us to define trigonometric ratios for angles greater than 90 degrees?
- 3What is the geometric relationship between the coordinates of a point on the unit circle and the basic trig functions?
