Someone teach me vectors please!!!

[arush002]

Got me 1/2 exam on thursday and i literally did not come to one class during the vectors topic because of methods and hebrew. Just need to know the basics - parallel vectors, etc....

Thanks,

Would be much appreciated.

Not sure about unit 1/2 but vector is basically a line that has a magnitude and direction...If there are two points A and B , you can find the direction by B-A
Let me know if you have any specific question

[arush002]

Just a question: How do you define / work out if a vector is parallel to another vector

[BigAl]

A vector is paralel to another vector if you can express one of them as a multiple of other. Generally given two vectors A and B if you can write where is a real number, you've shown that they are parallel
