Im finding some vectors quite challenging. Im not sure how i find the point on a vector line which is closest to the origin.
I know what it is perpendular to the orogin. So the vector product equals zero. However i end up forming quadratics which dont lead anywhere.
How should i approach these kinds of questions.
I am given the vector line equation and a point on the line. I am told to find the clostest point to the origin.
Thanks.
