# E-Maths Trigonometry Workshop Post Mortem

I completed my E-Maths Trigonometry workshop with a group of sportsmen and sportswomen. We do running, archery, basketball, badminton, bowling...

It was exciting and nervous to meet new faces... They hear my stories, I hear theirs.

For the workshop, I would like to discuss about bearings and the usage of sin formula through this question. Do you have any difficulties in E-Maths Trigonometry? I would love to hear from you! Leave your thoughts in the comment section below.

For bearings, pay attention to these 3 points:

• 3 figures
• Reference point
• Measured from North in a clockwise direction

For sin formula, you must know how to identify an angle and its corresponding length which are opposite each other.
