Note:
ATAN/DATAN functions can be used with a single or two parameters. Using ATAN(o,a) and DATAN(o,a) with two parameters provides for entering two sides of the right triangle in the function instead of entering the tangent value. For example, with a 3,4,5 triangle, where the two legs are 3 and 4, then entering ATAN(3,4) will return .6435011 and DATAN(3,4) returns 36.86989765. The functions are calculating the angle formed by the hypotenuse and the side opposite ("o" leg). To calculate the angle formed by the hypotenuse and side adjacent ("a" leg), you can switch the parameters.
