This gives practice for computing the absolute value.

How You Can (And Should) Get More Practice!

Below is a few practice problems of various difficulty, but you will need considerably more practice than one each. For that reason you should definitely use the green “Try Another” button in the top right corner at least two or three times to complete additional versions of these questions for more practice. You should keep using that button until doing these problems feels straight forward and easy, and then come back after a week or so of doing other stuff and try again to make sure it is still just as easy for you.

Practice Problems

Theoretically Easier Difficulty Problem

All we want is to compute a value, so it is “simply” (maybe not so simple in practice to actually compute it) a matter of plugging in the value and doing the arithmetic.
Consider the function . Compute .

Theoretically Medium Difficulty Problem

All we want is to compute a value, so it is “simply” (maybe not so simple in practice to actually compute it) a matter of plugging in the value and doing the arithmetic.

Consider the function . Compute .

Theoretically Harder Difficulty Problem

All we want is to compute a value, so it is “simply” (maybe not so simple in practice to actually compute it) a matter of plugging in the value and doing the arithmetic.

Consider the function Compute .
