Carmen – I’m not sure I follow the question, but you use ATan2 (or ATan) if you have x,y coordinates for two points and you want to find the angle of the line connecting them. If you are starting with angles and a distance you use Tan, Sin, or Cos to find x,y coordinates.

I’m just curious as to where the X and Y come from, if he started out with theodolite H and V angles?

Anyone wanting to follow the excellent advice of fzz, and use ATan2 in VBA, rather than ATan, look here:

Also why to write your own function, rather than use worksheetfunction.

Enter it as 10:50:59 (as a time), and use a custom format of hh°mm’ss”

Whether m is even or odd, 2m is even. 2m + n is even where n is even and 2m + n is odd where n is odd. I don’t know what ma is in your statement; I suppose it’s a typo. If 2m + n is odd, all you know about m and n is that n is odd.

I am trying to use excel to calculate the following, but do not know how to write the formula:
For all integers m and n, if 2m + n is odd then ma and n are both odd.

I need to provide a counterexample that shows this is not an accurate statement.

What I was thinking of doing was creating a quick formula for =2*odd number + odd number and dragging it until the answer was even, which would give me the counter example.

This seems so simple, but I cannot figure it out. Help!

karthikeayn:

You can figure this out for yourself. It's not difficult.

Search XL VBA help for 'square root' (w/o the quotes) and for 'cos' to find the VBA functions that correspond to those Excel functions. For most Excel functions that do not have a VBA equivalent, you can use the WorksheetFunction method as in Application.WorksheetFunction.SumSq(...) For more look up XL VBA help for 'sumsq' or 'pi'

please want formal of vb coding

(SQRT(SUMSQ(((E5-E8)*3600*30.9206),(((E6-E9)
*3600*30.81512)*COS(19*PI()/180)))))/1000

I still occasionally use my ‘Excel 5 Worksheet Function Reference’, probably about the last paper documentation Microsoft included with Excel.
