Introduction
Two or more vectors
can be added analytically without using any graphs. This can by adding the
components of the vectors along the co-ordinate axes or by adding the vectors
using geometry and trigonometry.
Pre-Requisites:
Vectors, Components

addition by components, Law of Sines, Law of Cosines
Activity:
Vector Addition-Analytical Method in physical world
Real Life Question:
How to add vectors
accurately without using graph sheet?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Law of Sines | In trigonometry, the law of sines (also known as the sine law, sine formula, or sine rule) is an equation relating the lengths of the sides of an arbitrary triangle to the sines of its angles. |
| Law of Cosines | In trigonometry, the law of cosines (also known as the cosine formula or cosine rule) relates the lengths of the sides of a plane triangle to the cosine of one of its angles. |
