Mechanics of machine force analysis with analytical method

In summary, the analytical method used in machine force analysis is a mathematical approach that involves using equations and formulas to determine the forces acting on a machine. This method differs from other methods of force analysis in that it relies on mathematical calculations rather than visual representations or computer simulations. The key components of this method include identifying and defining forces, creating free body diagrams, and applying Newton's laws of motion. It can be applied to various types of machines and has several advantages, including its precision, applicability, and acceptance in the engineering field.

So I was looking at this example problem in my textbook and I don’t understand how they got -168.1 degrees. The part I’m confused with is the first part of the 2nd picture, there’s a coma in the inverse tan, I don’t know what that means.

To resolve the full circle of slope or vector direction, the arctangent function needs both the dy and the dx components as parameters.
