I have a training class coming up on balanced and unbalanced three phase circuits. I am a engineering technology major and relied on my TI-89 to get me through circuits and motors 15 years ago. I purchased the Classpad because it was easy on my eyes. I was hoping that someone could provide me a link to any guides or tutorials on using Classpad for electrical engineering questions. I am having trouble figuring out how to enter polar coordinates, again what I remember of performing this calculations was done on a TI-89.
Thank you for all the help,
