The Del operator
i'm going through some tricky vector product arrangements and rearrangements. some involve expressions like phi del (i mean the symbol phi followed by the operator del) - no dot or cross product involved. what exactly does this mean? is it the same as del phi? simply the gradient of phi? i can't find any websits which clarify this
Provide a counter example to prove why the following is not a vector space.
A= ((x,y) within R2 / x>=0)
I'm not sure why this is not a vector space. If I remember correctly, a vector space is commutative and associative?
SQA Higher- Vectors
I just cannot understand this question but i know the answer is (-5,-5, 7) I really want to how it's done, this is the question:
VABCD is a pyramid with the rectangle base ABCD The vectors of AB , AD and AV are given by: AB = 8i+2j+2k AD=-2i+10j - 2k AV= i +7j +7k
Express CV in component form ?
Help will be greatly appreciated
