Vectors physics homework -- Addition of two vector forces
Click For Summary
SUMMARY
The forum discussion focuses on solving a physics problem related to the addition of two vector forces. Participants emphasize the importance of clarity in presenting mathematical work, specifically mentioning the use of LaTeX for formatting equations. A user named Ahmad is advised to correct his notation, particularly the confusion between the variables x and θ. Additionally, the discussion encourages finding equations that relate cos(θ) and cos(θ/2) to aid in solving the problem.
PREREQUISITES- Understanding of vector addition in physics
- Familiarity with trigonometric functions, specifically cosine
- Basic knowledge of LaTeX for formatting mathematical expressions
- Ability to interpret and manipulate equations
- Research the principles of vector addition in physics
- Learn how to use LaTeX for mathematical formatting
- Study the relationship between cos(θ) and cos(θ/2)
- Practice solving vector problems with clear notation
Students studying physics, educators teaching vector mechanics, and anyone looking to improve their mathematical presentation skills in forums.

Welcome to the PF.
Your attachment is sideways and pretty hard to read. Can you please type your work into the forum? That makes it a lot easier to respond.
There are math symbols in the Edit bar above the edit window under the √ symbol, and there is a tutorial about how to use LaTeX under the Help pages (see INFO at the top of the page). Thanks.

Hello Ahmad, 
!
My neck still hurts from trying to read your picture ( I use a desktop, not a phone). For the sake of others I re-post it:
I notice your x is not the ##x## in the exercise (which is your ##\theta### ) so that deciphering isn't just painful, but also confusing.
As @berkeman (who types faster
) says: could you re-post and explain what it is you write down?
In the mean time you can try to find a relevant equation that links ##\cos\theta## and ##\cos(\theta/2)## and post that too
Oh, and: read this
