My teacher likes to challenge us, well sometimes simple problems as this get me stumped. I think i got the refrence angles messed up, i get confused with them when i have to draw them reflect on the x axis. Anyway thanks. Or the convertion to radians.

r = sqrt [ (-6)^2 + (1)^2 ]    =  sqrt (37)

 

To find theta, we have

 

atan ( 1/ -6)   = -0.165148677415

 

However.....this point lies in the second quadrant so we must add pi radians to it.....and we have

 

-0.165148677415  + pi   ≈ 2.9764    rads

 

So   (-6, 1)  rectangular  =

 

(r, theta)   = ( sqrt (37),  2.9764)

 

 

cool cool cool
