When handwriting vectors, students should write a squiggle underneath the letter to indicate that it's a vector. In examinations, is it marked incorrect if students do not write the squiggle underneath and they only write the letter?
Can someone please help me with vectors. For some reason, whenever I do any of the maths involving finding the distance between a point and a line, the answers never match. Can someone give me a tip on how to solve this type of problems.
When I solve it I find the unit vector in the direction...
