hellooo everyonee:)
well this week everyone has really been busy with the carnival ball and what not. But despite all the hectic over that i must admit that the week was pretty productive for my advanced math and physics classes anyway..but anywho we learned a lot vectors again. When we were'nt learnning about vectors, we were working on our ALEKS which is gonna be done pretty soon.

we learned how to tell if vectors were parallel or perpendicular..you can do this by doing dot product. if the answer is equal to zero, then vectors are perpendicular.

ex. ( 2,3) (0,0)
(2*0)+(0*3)
=0+0
=0
therefore, the two vectors are perpendicular :)

in order for two vectors to be parallel they must be proportional. Here is an example of two vectors that are proportional, and parallel.

ex. x(1,2) y(2,3) z(3,4)

2/1=3/2=4/3
2=3/2=4/3
so noo, these vectors are not parallel which is too bad :(
