### EJSS vector sum model

Update 31 July 2015 now with examples by Ezzy Chan

## Example 1 |V₁|=120,ϑ₁=60°,|V₂|=80,ϑ₂=105°

 |V₁|=120,ϑ₁=60°,|V₂|=80,ϑ₂=115° example 1 by ezzy chan
 |V₁|=120,ϑ₁=60°,|V₂|=80,ϑ₂=115° example 1 solution by ezzy chan

## Example 2 |V₁|=12,ϑ₁=0°,|V₂|=9,ϑ₂=90°

 |V₁|=12,ϑ₁=0°,|V₂|=9,ϑ₂=90° solution by ezzy
 |V₁|=12,ϑ₁=0°,|V₂|=9,ϑ₂=90° example by ezzy

## Example 3 |V₁|=400,ϑ₁=-90°,|V₂|=500,ϑ₂=60°,|V₃|=500,ϑ₃=120°

 |V₁|=400,ϑ₁=-90°,|V₂|=500,ϑ₂=60°,|V₃|=500,ϑ₃=120° example by ezzy

 |V₁|=400,ϑ₁=-90°,|V₂|=500,ϑ₂=60°,|V₃|=500,ϑ₃=120° example 3 solution by ezzy
