Assigned Week 4 Block 11 by Dr. Rickert. Due by 5PM Tuesday, October 5.
Find the size and direction of the vector 7 i + 5 j .
> v1 := vector([7,5]):
size (magnitude) is equal to the square root of the dotproduct of itself
> v1m := sqrt(dotprod(v1,v1));
direction is equal to the unit vector
Find two vectors that are parallel to the vector 10
Be sure to explain how you know that they are parallel.
> v2 := vector([10,20]):
these vectors are parallel because the slopes are the same as the original vector, as determined by y/x
Find a vector that is perpendicular to the vector 5
Be sure to explain how you know that it is perpendicular.
