i was taught in my physics lecture that Work =Force *distance *cos(A)
to my belief this is the dot produict and used to measure area.
in my maths lecture two vectors using the cross product is also used to find the area ie: N x M = N*M*sin(A)
i thought that one product was used for area and the other for a different use along the lines of the projection of one vector upon another?
help
