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.
What is arctangent? Initial disclaimer: This is by no means intended to be a full-blown explanation of trigonometry or its functions. This is just a helpful service to everyone who is coming to arctangent.net presumably seeking help with this particular function. arctangent (atan or tan-1 on some calculators) is used to calculate the angles of a right triangle. It works opposite of the tangent function. While tangent will find the ratio of the two sides of a right triangle when given an angle, arctangent can find the angle given the ratio.
