Question

Will Fan And Medal :)

I need help filling out a study guide.

1. How do you convert between radians and degrees?

2. What does it mean for angles to be coterminal?

3. What is ASTC used for?

4. What are examples of periodic functions in the real world and why are they considered periodic or cyclic?

Answer 1

http://www.mathwarehouse.com/trigonometry/radians/convert-degee-to-radians.php this helped me with the first question

Answer 2

Coterminal angles are found by adding or subtracting 360 degrees or any whole number multiplied by 360 degrees.

When we add 360 to -120, we get 240 which would be the first positive coterminal angle for second

Answer 3

radians to degrees: value times pi over 180

Answer 4

thanks

Answer 5

do you think you can help me with the last two?

Answer 6

i think

Answer 7

ok, i figured out the third one. But the last problem is still confusing.

Answer 8

the voltage coming out of a wall socket is a example periodic functions in the real world.
