=HOW TO:= = Calculate the sum of vectors using law of cosines and component methods. =

=I chose this topic because it allowed the class to discover how to use simple trig in the real world. I also chose this topic so I could better explore the component method, seeing as it was difficult to grasp visually. Hopefully the visuals provided in the video help to better your understanding, because it definitely helped me.=

**__Vector:__** a quantity that has a magnitude as well as direction
== __**Simple Trig**__: Law of Sines, Law of Cosines, and (SohCahToa) rules = = = To Begin: Watch this video as a thorough explanation of the topic! =

If it helps, it is recommended that you follow along with the running example throughout the video. This way you have hard notes and a decent example to look back at.

=Let's sum up the Component Method in words and Simple Steps!=



__http://phet.colorado.edu/en/simulation/vector-addition__ - use this tool that was available to us to practice and understand the component method better

=Now Let's Sum up Law of Cosine in a few simple steps!=



= NOW LET'S PRACTICE SOME PROBLEMS! =

= = =Let's Try an Example of Both Law of Cosines and Component Method. This written out may help you understand.= == = = =Law of COSINE= ==

**ANSWER**

**ANGLE TIME**
= Challenge Alert! Try Component Method on your own. The answers are given above using Law of Cosine, so you are able to check. Look at the steps above, or the video explanation if you need help.=

= = =CHOOSE WHICH METHOD IS BEST FOR OUR NEXT EXAMPLE.=

=//Please try before reading on.//=

**YOU GUESSED IT!!** Component Method would be the optimum way to solve for the Resultant Vector.


 * TIP: Many people get hung up on finding the right triangles while doing component method. If you can't visualize it, then just focus on the components. This is what helped me the most in this section. Look above at component steps for help with the equations.**

// This problem is a good example of simply using the components without a confusing picture. In this case, there are three sides (components) added together. //
