TI 83/84 Graphing Calculator
Phasor Calculations Instructions
In order to use a TI graphing calculator to do phasor operations, the first thing to know is that everything must be done in Cartesian form. If something is given to you in polar form you will have to convert it by hand or use the “Polar” program that can be downloaded from the IT website.
The real part is: Magnitude * cos(θ)
The imaginary part is: Magnitude * sin(θ)
Before trying anything, make sure your calculator is in the correct mode:
“FUNC” and “a + bi” should be selected.
Everything can be input in your calculator in the following format:
123 + 456i
The “i” is found by pushing the 2nd key followed by the “.” key.
You can do all your calculations in the Cartesian form. There is no need to convert to Polar for anything.
If an answer is requested in polar your calculator will do the conversion for you. Just push “MATH”, “CPX”, 7 and hit enter. It will show the answer in Polar form, but in the calculator’s memory it is still stored in Cartesian so you can continue doing operations.
You can also save your Cartesian answers as variables in your calculator by pressing the
STO button and then pressing which variable letter you would like to store it as.
Mathematical operations can be done using either the variables i.e. X/Y or by typing it in with parenthesis i.e. (6 + 2i) / (15 – 72i)
