Is it possible to add & subtract vectors (or even get an approximation) using polar notation only?
I want to do this avoiding Square roots, cos sin or tangents if possible!! Or at least minimise their use.
Answers:
The simple answer is no. If you have two vectors written in polar notation and you want to add them, you pretty much have to go through the rectangular description of those vectors. The trig functions and square roots simply cannot be avoided. Addition and subtraction are defined in the rectangular system. The conversion back and forth to the polar description requires the trig functions, etc. This *is* the easy way!
umm okay im confuzzled now
if you stay in polar notation, then you will HAVE to use trigonometry functions to make additions and substraction, except, of course, when the 2 vectors are colinear or perpendicular. But then, you'll only be using them without knowing it.
You can't, sorry!
eh?
Only if the vectors are all pointing in the same or opposite directions, then you and add and subtract vectors.
If you spent as much time actually studying the trig functions, roots, etc. as you waste trying to figure out how to get away with not using them, you'd have it figured out bt now.
