Hello everyone. I am trying to do a polar to rectangular conversion on my simple Casio fx-260 and it gives an error. Here is the Polar
-0.15, 170degrees. No matter how I state the angle, it gives and error. Any clue’s?
 

Hi,

"-0.15" is the length of a vector.
Why don't you use a positive length?

You may use the "angle + 180°" to invert the direction.

Thanks, that is the answer. I mistakenly included the (-) in my calculation. So actually here is what I was doing,
2.2,0deg - .15,170deg. I put in -.15 but should have been just a positive vector. Man o man. Sometimes.
thank you so much for the help. I had my eyes closed.
 

Yes, the positive radius works just fine.
