Assuming you're in the complex mode, SHIFT ENG. The ENG key is above the 8.

How to use complex numbers in a matrix using casio calculator


Sorry, you cannot do that. If matrix is small split it in imaginary part and real part . This will double the dimensions. But this family of calculators you can have matrices with dimensions at most equal to three. Do the calculation by hand.

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 complex numbers


The fx-350MS does not have complex capabilities. You can do complex calculations the old-fashioned way, breaking each complex number into its real and imaginary components.

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.

How to get the imaginary numbers on the 115es casio calculator? It is in purple and i cant get it with shift.


You need to be in complex mode before you can do any calculations involving complex numbers. Press MODE 2 to switch to CMPLX mode. When you're done, press MODE 1 to switch back to COMP mode. (Yes, the names are confusing. I didn't pick them.)

Where is the i button on the TI 86?


There isn't one. If you're entering a complex number in rectangular form, separate the real and imaginary parts with a comma (left of the 4). If you're entering a complex number in polar form, separate the magnitude and the angle with the angle symbol (2nd comma).

How do i calculate using base numbers? Ex: How do I use this calculator to find 2 to the 12th power, without having to go: 2x2x2x2x2x2x2x2x2x2x2x2=4096?????????????


If you are using scientific calculator; there must be a symbol " ^ ". It is for power.
You can use it like this... 2^12=4096

If there isn't any such symbol... then it won't be easy.

2^12 = 4 ^ 6 = 16 ^ 3 = 16x16x16 = 4096

I hope this was helpful.
