Hi all, I love this forum. I am a electronics student just needing a second opinion on a equation. I am calculating impedance in my TI-89 and just need a second pair of eyes.

Equation is (38.1 @ 0° + (33 @ 90°) + (11 @ -90°) > polar = 44.000 @ 33°.

Is that what you get as well?

Thank you,

TDH

 

Hi there,

I get 43.9956 @ 30.0033°

I've only shown the result to 4 decimal places since that's where you may have the angle term incorrect.

 

Yes that is what I got as well, just typed it incorrect. Thank you for your help, it is much appreciated!
