trigonometry

Using trigonometry, it is possible to calculate the path an object will follow when hitting the inside walls of a closed rectangular area. Here are the relevant points of the code: The input variables are the starting position and angle, between 1 and 89 degrees. The values are hardcoded but...

If you need to ascertain the radius of something circular and all you have is a segment, you can use this spreadsheet to do so. Just take two measurements and put them into the two cells and the spreadsheet will reckon the radius, as well as some other trigonometric stats. Here is a photo of...

Could you direct me toward some class modules (VBA or VB) to calculate the moon ( and planets ) rise set altitude azimuth for locations ( Lat, Lng, Elevation ). Most I can find are about 1998 models using UDF 's on worksheets. Need to graphically present these for high school students.

why does worksheetfunction.acos(c) take about 10 times the time of the atn( sqr(1-c*c)/c)) method :eeek::eeek:

I have been working on a problem and through all of my research I have been unable to find an existing resolution. I do not have the required math knowledge to produce an elegant solution. There are several examples of working (and very elegant) line - line intersections with either complete...

I have been pulling my hair out trying to enter this equation and have no idea how to get this to work properly or what is the right format to get the answer out of Excel. 365 COS (130)
