- How do you convert 108 degree to radians?
- How can you use the conversion factors pi/180 and 180/pi to convert between degrees and radians?
- How do you convert 8*pi/5 radians to degrees?
- How do you find the exact value of tan 7*pi/6?
- How do you find the exact value of sin 3*pi/4?
- How do you find the exact value of sec pi?
- What is the radius of a circle if arc length is 3pi units when the central angle is 2*pi/5?
- What is the formula for arc length?
This lesson kicks off a series on trig review. Several example problems are shown in this video including converting between degrees and radians and simplifying, finding values of trig functions given an angle measure in radians, and finding the radius of a circle given the arc length and central angle. All steps involved in solving all problems are shown and explained very well.
