Projectile motion equations using Euclidean Geometry only

Ntwede

Here is a spreadsheet I made to solve projectile motion problems. It uses only euclidean geometry to solve for the answers, but it gives the answers as slopes, not angles. All variables entered also must be in slopes and not angles. I added a section that does the conversion between the two (just a TAN and ATAN function) to help with getting the slope when you know the angle though.

Anyways, as far as instructions go, the top row of boxes starting on the left are the boxes where you enter the known variables, and the answer will be given in the boxes below. (Not all problem types are solve able using this, but It does the major types of problems such as distance, slope that will make projectile hit the target, max range, time of flight, Etc.)

Please tell me what you think, and give suggestions/point out problems please. =)
