Resolving Vectors Anywhere

To resolve vectors outside quadrant 1, the procedure is no different than what you learned previously, except you must take into account the CAST rule.

Let’s begin with a quick video example:

Occasionally, you may need to couple your knowledge with what you know about the cosine law. This is especially true when you’re looking for an unknown angle separating two vectors of known magnitude. Let’s watch an example:

Finally, you may be asked to find the resultant vector when given 3 or more vectors. While these questions aren’t complicated, they do take a while to complete. Just make sure you don’t make any careless calculator errors in the process.
