amazing explanation i just have two inquiries, to find the angle is it always -tan^-1(w/3)? or does it vary depedning on the equation? and if it varies what is the general equation for it? and the second is for the magnitude. same thing is it always 6/radical(w^2 +9) or it depends on each case? and if so also please give the general equation with an explanation, thank you! DO NOT REPEAT THE QUESTION JUST ANSWER THESE INQUIRIES PLEASE AND THANK YOU.
