Professor Burger shows you how to add and subtract vectors and use scalar multiplication to elongate or shrink vectors while maintaining their direction angle. The magnitude of a vector can be altered with scalar multiplication. A scalar is simply a number (positive or negative or a fraction) used to multiply a vector by, with the vector keeping its same direction and changing magnitude. Vectors can also be added and subtracted by simply adding or subtracting the components. It is also simple to find the answer graphically by creating a parallelogram with the two vectors, which Professor Burger demonstrates.

Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Precalculus.

Glad you liked this lesson. We are trying to add a wide variety of our Thinkwell catalog so hopefully we can cover some of those topics for you fairly soon.

Check out our full site in the description and take a look at our whole catalog, you just might find what you're looking for. Best of luck!

Burger teaches this video better than my math teacher, i started watching the videos in geometry and they help me study for PreCal, THANKS!!

i needed to know how to add vectors, not do the scalar thing :( might want to change the title or something, it was kind of misleading.

LOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOL '' OH LA LAA LAAAA, soooooooooooo uncalled for.
