Homework Statement


Vector B is given in polar notation as (6,-130degrees). In rectangular notation vector B is what?


Homework Equations


For this problem, take all angles between -180 and +180.


The Attempt at a Solution



I got an answer or -3.85 and -4.59. However they were the wrong answers. I suspect it has something to do with the all angles between -180 and +180 part. I took (6,50degrees) and put it in the calc. and got that answer -3.85 and -4.59. What am i doing wrong????

What exactly did you do?

I put [6,50degrees] in the calculator and solved it for rectangular notation. Which should give me the x and y values of the rectangular notation.

If you use calculators to solve your problems, you'll never know how to solve them, right? So, what is the relation between polar and rectangular coordinates?
