I have a funny problem with complex numbers calculations. I can not simply enter a complex number with radius and angle, for example: 3<45deg. When I enter the number using angle symbole in OPTN, I receive a "Wrong argument type" error. I can do it easily in simple casio calculators other than classpad and I remember I could do it with my classpad during my MSc course. It would be thankful if someone could help me.

HI
You can simply use the form 3xe^(pi/4)+5xe^(pi/6)+...
Also the commands: cExpand(),compToPol() may help you.[in main window :action>complex>~...]
Have you written any program about this calculations?
good lock

Thanks. I can use different formulas, but in microwave engineering, you need to use several complex parameters in format of 'radius,angle'. I need an straight forward solution, and no extra conversions. You can do it directly in most simple calculators.

I found what you realy want!
You must enter them as vectors in braces like: [3,<(45)]
Don't forget to attention to the angle unit !!
Hoping to be useful

In my CP-FX400 if you want to use a complex number in the polar version you need to enter it the following way:
20|38
in the calculator, the number 20 is the 1st argument and the number 38 is the 2nd argument --> |(20,38). You also need to enable the complex numbers mode.

Hi...
I seem to have a problem with complex numbers. Maybe a configuration issue but I'm obtaining wrong results for the following calculairon:
(15-j10)x14.36|-134.4
The result should be 258.87|-102.7
but the my ClassPad's result is 258.87|259.29
Can't figure out why! Any ideas?
Though, the following calculation:
(10-j20)x12.52|50.6 = 279.96|-12.75
which is correct with the real value!

I got it...
Calculator automatically converts negative angles in their complementary values, meaning -102.7 = 257.3-360
