changing to polar coordinates
(5,-12)
i get 13 , -1.1760
my closest option is 13, 292.62
does the -1.1760 convert somehow to 292.62???

I got theta as -67 deegres, that should be close to -1.2 radians. Hmm.

yeah thanks

anonymous · Answer

How did you get 292.62? :-)

anonymous · Answer

It's the -arctan(12/5).

anonymous · Answer

no i got the 1.1760 wel what u got my option on my work is 13, 292

anonymous · Answer

That is in deegres, I suspect. So, it's more or less  correct.

anonymous · Answer

yeah im going with it anyways thx

|dw:1336019189466:dw|theta here is in radians, alpha is deegres. They are more or less on the same arc. I got 292.61, but that's precision :-)
