If you're positive then I'm sorry to say that I'm negative...

The power of 10 should be 2 instead of 3. Plz check the Question again... Did you copy it EXACTLY??

Have a look at Post #5 above.

Try to Approximate the Numerator and Denominator to the nearest possible multiples of 5 or 10 and then you can simplify quickly!

I'll give you a few examples.....................

You can do a Quick Approximation but its hard to do it Quickly unless you are real good at Multiplication/Division of Large numbers!!

He is looking for a General Solution for the lengths of all such XY's for all Regular Polygons (no. of sides > 4)!
I don't know if thats possible or not...
May be, he'll come up with a General Approach instead!?

I showed him your reply and...
mmmm... Can we try solving it using Euclidean Geometry only?
Sort of... NO USE of co-ordinate system and vectors!
(he says he does 'em using Similar Triangles and Trigonometry )

Thanks for looking into it!

s is -2 coz its meter per second squared (unit of acceleration).

understand it like this..

As you can see, it appears to be a ratio but is rather a "Rate of Change w.r.t Time"!

I can't find the remaining word anywhere...
I can spot only "DAET" at the Top of Fourth Column!??
