E N D
Vocab/Formulas • Radian: length of the arc formed by an angle • another unit of angles other than degrees • Arc Length: • θ must be in radians 1 unit
Example 2: Solve for x if 0≤x≤2π and cos x = 0.6. (Think about the range of answers…is there just one answer?)
Example 3: Find the arc length for with a radius of 5. a.) in radians. b.) in degrees
