Now, I have unscrambled all but three of these...but will not tell you which. To raise the stakes, I will send a great prize to the first person (or computer) who submits unscrambled versions of all twenty words...and eases my frustration.

**Hint:** Find a list of trigonometry vocabulary...and look for key letter groups.

**Solution Commentary:** I do not have one...Until proven otherwise by someone's submission, I claim that either the author or the typist made some errors in compiling this list. That is, in the three scrambled words I cannot undo, if I change one letter, it is do-able and makes sense.

The title itself (copied directly from the issue) seems to be a give away for some inherent confusion. Should't it be "scramble"...not "scrabble"? And, why is the word "mathematical" even included...or is their a non-mathematical trigonometry I am unaware of? Note: I checked the *Urbane Dictionary* just to be safe here....

Finally, G.W. (WWU) offered this confirming response: "Here are my answers to the scrambled trigonometry problem you posted. I believe you had problems with numbers 8, 16, and 17. For these ones, I checked in a word descrambler and found there are no such words that exist. I think I know the answers but they were posed incorrectly so I feel I need to explain myself. For number 8, if they are missing the letter "C" the word is adjacent. For number 16, exchanging an "A" for an "E" gives cosecant. Changing an "E" into a "C" in number 17 gives circles. All of these could be easily explained as typos by the journal *Factorial*, whose editorial department might have been having a bad day.

Here are the other answers, in case I was incorrect in my assumption.

- Function
- Tangent
- Secant
- Cosine
- Radians
- Angles
- Triangles
- (AdjaCent)
- Hypotenuse
- Cotengent
- Arcsine
- Periodic
- Measure
- Equation
- Degrees
- (CosEcant)
- (CirCles)
- Opposite
- Sine
- Radius
