Turn calculator ON.
If you see no icons, press [MENU] key.
Use Arrows to focus on RUN and press [EXE]
Press [OPTN]
Among the TABS that appear at the bottom of screen you have CPLX.
Press [F3] to activate it.
The menu TABS that are displayed allow you manipulate complex numbers:
F1 :i imaginary unit i
F2: Abs takes the absolute value of a complex number.
F3:Arg, gives the argument (angle the complex number makes with the positive X-Axis)
F4: Conj calculates the Conjugate of a number.
F5: ReP extracts the Real part
F6:Imp extracts the Imaginary part.

For other operations use the operation keys [Plus] [MINUS] [*][/] [X^2] [Square root]. Be careful using the universal power key or the xroot key as it may lead to a Memory error.

Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
New users get to try the service completely Free afterwhich it costs \$6 per call and covers almost anything you can think of (from cars to computers, handyman, and even drones).
Goodluck!

Putting in the imaginary number problems

The 30XIIs doesn't deal with complex numbers directly. You can separate the real and imaginary parts and deal with them separately.

How to put in the imaginary numbers on calculator

The 30Xa doesn't work with complex numbers. You'll have to work with the real and imaginary components separately, just like they taught you in class.

I can't use an imaginary number in a sigma notation

The summation function only works in the real mode, not the complex mode. You'll find that the same limitation applies to many other functions, such as the integration.

See page E-42 of this manual for the functions that are allowable in complex mode.

How to find exponential power of imaginary part in casio calculator

This calculator can do simply algebra with complex numbers-addition, subtractions, multiplications, extract the imaginary and real parts- but not much else. Sorry, calculating exponentials or complex numbers is not within its capabilities.

Bibbliography of real numbers

Real Numbers are just numbers like: 1 12.38 -0.8625 3/4 ?2 1998 In fact:

Nearly any number you can think of is a Real Number
Real Numbers include: Whole Numbers (like 1,2,3,4, etc) Rational Numbers (like 3/4, 0.125, 0.333..., 1.1, etc ) Irrational Numbers (like ?, ?3, etc )

Real Numbers can also be positive, negative or zero.
So ... what is NOT a Real Number? ?-1 (the square root of minus 1) is not a Real Number, it is an Imaginary Number Infinity is not a Real Number And there are also some special numbers that mathematicians play with that are not Real Numbers
Why are they called "Real" Numbers?

Because they are not Imaginary Numbers.
The Real Numbers did not have a name before Imaginary Numbers were thought of. They got called "Real" because they were not Imaginary. That is the actual answer!
The Real Number Line The Real Number Line is like an actual geometric line.
A point is chosen on the line to be the "origin", points to the right will be positive, and points to the left will be negative.

A distance is chosen to be "1", and the whole numbers can then be marked off: {1,2,3,...), and also in the negative direction: {-1,-2,-3, ...}
Any point on the line is a Real Number:

• The numbers could be rational (like 20/9)
• or irrational (like ?)
But you won't find Infinity, or an Imaginary Number.
Real does not mean they are in the real world They are not called "Real" because they show the value of something real.
In mathematics we like our numbers pure, if we write 0.5 we mean exactly half, but in the real world half may not be exact (try cutting an apple exactly in half).

When I attempt to use hyperbolic functions for complex numbers i get a domain error

Have you checked the calculator's manual to see if the calculator is able (natively) to handle functions of a complex argument. It is able to handle simple algebra with complex numbers, powers, roots, solving a polynomial equation.
For this calculator, the hyperbolic functions must have a real argument otherwise you get a error. But just to make sure, try the exponential function with i (imaginary unit) as argument. If it comes back with a domain error you have your answer.

5 2nd [MATH] F5 MORE F4 ( 0 , 1 ) ENTER

2nd [MATH] brings up the Math menu. F5 goes to the Misc menu, and F4 is the x-th-root function. ( 0 , 1 ) puts in the complex number i: that is a real component of 0 and an imaginary component of 1.
