The quiz questions are designed to test your knowledge of the material covered in this hour . The answers to the questions follow.

Quiz

1:	What is the result of Math.min(10,Math.max(5,a)) when a is equal to 12? What is the purpose of such a statement?
A1:	The answer is 10. Math.max(5,a) resolves to 12; then Math.min(10,12) resolves to 10. The purpose of code like this is to make sure that the variable stays between two numbers . In this case, the result will never be less than 5 or greater than 10, no matter what "a" is.
2:	If a movie clip is halfway around a circle, how do you get its horizontal position on the screen?
A2:	Use Math.cos with a value of 3.14, or Math.PI . Math.cos returns the horizontal position of a point on a circle. A complete circle is 6.28, or two times pi, so halfway would be 3.14 or pi. You also need to multiply the result by the radius of the circle.
3:	What is the largest possible value returned by Math.random()*7 ?
A3:	The largest value of Math.random is slightly less than 1.0. So the largest possible value of Math.random()*7 is slightly less than 7.0.
4:	If you use duplicateMovieClip to create a copy of a movie clip instance, what happens to the original instance?
A4:	Nothing. It is still there and any script assigned to it is still active.
