Sine and Cosine Rules
The sine rule relates the angles and lengths using this equation:
The Cosine rule relates them using these equations:

| Lesson 2 | ||
| Learning Outcomes | To be able to resolve vectors into their vertical and horizontal components | |
| To be able to add vectors and find the resultant by resolving them | ||
| To know what equilibrium is and how it is achieved | M.BENYOHAI |
In the last lesson we looked at how we could add vectors together and find the resultant. In this lesson we will first look at ‘breaking down’ the vectors and then finding the equilibrium.
