"Solve problems using either radian measure or trigonometric ratios in the unit circle."
"Convert between angle measures in degrees and radians."
What you'll learn
- Define one radian as the central angle that subtends an arc equal in length to the radius, so that theta = s/r is a unitless ratio independent of the circle's size
- Derive pi radians = 180 degrees from the circumference
- Explain why s = r*theta requires theta in radians
- State the radian measures of the angles pi/6, pi/4, pi/3, pi/2 and order them by size
- Determine whether an unlabelled angle in an SAT problem is in degrees or radians
