AI Thread Summary
The discussion focuses on simplifying a center of mass equation involving tension components and angles. The equation presented is [T_2*sin(theta2)] / [T_1*sin(theta1) + T_2*sin(theta2)]. Participants are seeking a trigonometric identity that can help simplify this expression effectively. Visual aids are provided to assist in understanding the problem. The goal is to identify the appropriate trigonometric identity for simplification.

1. This was actually a center of mass problem, so I got the equation below:



2.[T_2*sin(theta2)] / [T_1*sin(theta1) + T_2*sin(theta2)]



3. This is part of a solution I obtained for a physics problem. I know there is some trick with a trig indentity that I can use to simplify this. What is the identity?

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
