Hi, I get really confused when to use the cos function or the sin function. for example, I was looking at this yesterday and thought the other way around of the correct answer. Why did it chose sin function for tension and cos function for the normal force?(adsbygoogle = window.adsbygoogle || []).push({});

This problem doesn't explain why it chose the trigometric function for each question.

Thank You.
