Craig Thanks again for making me think. Given the square root of the x squared will be positive x. Given the absolute value of x will be positive x. Then x + (H-h) - x = H-h Therefore, unless H-h changes, no matter what the input angle is, the initial equation stated will give the same value for any angle input. Beginning to wonder who actually took my SAT's 39 years ago ;-) Bill > I remember from statistics that the process of squaring a number then taking > the root of it is for the purpose of removing negative > numbers.
