The scales provide the tangent or cotangent of the meridian altitude. In the last equations [sigma] = ds is the scalar arc element for (P) and (P'); [lambda] is cotangent angle, i. From 40[degrees] to 50[degrees], cotangent is a decreasing function.
The arctangent function is the inverse function of y = tan(x). arctan(y) = tan-1(y) = x+ kÏ. For every. k = {...,-2,-1,0,1,2,...}. For example, If the tangent of 45Â° is 1: tan(45Â°) = 1. Then the arctangent of 1 is 45Â°: arctan(1) = tan-1(1) = 45Â°.
