Question about Sharp El-520x Advanced Scientific Calculator White Bp Package Of 5

I have to sum (for example) 2 complex number: 4+5i + 6+3i= On the second line of my EL-520X I see: 10.0000. Where is the 8i ? Thanks a lot.

If you press the setup key then 1 under FSE it will say TAB (0-9)? enter the amount of decimal places you want and it will change that for you.

SOURCE: Half-life exponential problem. Can't get the same answer as example

Hello,

Here is how you enter it.

[+/-]0.693/8x4[2ndF][e^x][=] result is 0.7071588193 or as you wrote 0.7071

some calculators show an error message if you enter the [+/-] (the negative of a number before the number itself).

In that case enter 0.693 then press [+/-]. the calculator should put a small - sign before the 0.

You can try

0.693[+/-][x]4[/]8[2ndF][e^x][=]

Hope it clarifies things.

Hello,

I do not think that this line of calculators can do operations on complex numbers.

Hope it helps.

Thank you for purchasing the SHARP Scientific Calculator Model EL-W531/W531G/W531H/W531HA/W535.

About the calculation examples (including some formulas and tables), refer to the reverse side of this English manual.

Refer to the number on the right of each title in the manual for use.

After reading this manual, store it in a convenient location for future reference.

Notes:

• Some of the models described in this manual may not be available in some countries.

• This product uses a period as a decimal point.Displaying calculation results

When possible, calculation results will be displayed using

fractions, r, and ?. When you press U, the display will cycle

through the following display styles:

• Mixed fractions (with or without ?) ? improper fractions (with

or without ?) ? decimal numbers

• Proper fractions (with or without ?) ? decimal numbers

• Irrational numbers (square roots, fractions made using square

roots) ? decimal numbers

Notes:

• In the following cases, calculation results may be displayed

using r:

• Arithmetic operations and memory calculations

• Trigonometric calculations

• In trigonometric calculations, when

entering values such as those in

the table to the right, results may be

shown using r.

• Calculation results may extend off

the edges of the screen. You can

see those parts by pressing l

or r (depending on whether the left or right portion is

hidden).

I would be interested in knowing the model number of the Casio calculator that can do prime factorization. I know and own several Casios (scientific and graphing) calculators and I have not found one that does it. Some graphing calculators are able to perform the factorization with the help of an additional program.

The sum is the result of an addition.

When you add two numbers, the result you find is the sum of the two numbers.

15+10=25. The sum of 15 and 10 is 25.

You cannot program it. You can only use the features that were implemented on it at design time. These features are detailed in the instruction manual. Check the appendix: examples of all the possible calculations are given. The manual is available on the Casio website for downloading.

Apparently your problem has a complex (non-real) answer. By default the calculator works with real numbers and gives this message when the solution is not real.

You can change this by pressing the MODE button, down-arrow to the "REAL" line, right-arrow to one of the two complex display modes, then press ENTER and 2nd QUIT to save the change.

If you still have problems, could you post an example that produces this message?

Formulas are used to specify calculations based on values in designated cells. Excel supports basic calculations as well as statistical, trigonometric and other specialized functions.

Formulas used in Excel must follow a certain syntax.

- All formulas begin with an equals sign
**(=)**. - Some formulas use operands such as
**+,-, *,/**for addition, subtraction, multiplication or division.

For example, the formula =A1+A2+A3 would add the contents of cells A1, A2 and A3. - Other formulas refer to different functions such as SUM, AVERAGE and others.

For example, the formula =SUM(A1:A3) would add the contents for the range A1 through A3. - Formulas can be
**combined with operands.**

For example, the formula =10*SUM(A1:A3) would add the contents cells A1 through A3 and multiply them by 10. - Functions can
**be nested within each other.**

For example, the formula =SQRT(10*SUM(A1:A3)) would take the square root of ten times the sum of cells A1 through A3. When functions are nested, it is important that the number of left parentheses match the number of right parentheses.

Code example:

// all fields are numeric type

USE example APPEND BLANK REPLACE field_a WITH 25, field_b WITH 4, field_sum WITH field_a + field_b, field_prod WITH field_a * field_b APPEND BLANK REPLACE field_a WITH 60, field_b WITH 5, field_sum WITH field_a + field_b, field_prod WITH field_a * field_b

Result: field_a field_b field_sum field_prod 25 4 29 100 60 5 65 300

Don't use keywords as field names (ex. SUM).

Let us first set the record straight: Your calculation is a division not an addition. Be it as it may, the result you obtain is correct the fraction is equivalent to the one you entered, the difference lie in the fact that the calculator reduces the (entered) fraction to its simplest form.

Both the numerator and the denomonator have been divided by 15.

If the result is already calculated and displayed, press the [S<=>D] key It will convert a fraction or radical to decimal. This is always possible. If the result is decimal it may be converted to a fraction or a radical (Not always possible).

If the expression to be evaluated is still in the command line and you have not pressed the [=] key, you can force the result to be displayed in decimal format by pressing [SHIFT][=] instead of just [=].

More permanently. If you do n o care for fractions and radicals, set the Input/Outpout mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]

To calculate the reciprocal of a numerical value you can use

1 [/] 13 [EXE] result is 0.07692307692 or

13 [EXE] to have 13 in Ans memory (displayed) and [SHIFT][ ) ] [X to -1] [EXE].

For such a simple number as 13, calculating its reciprocal the second way seems ridiculous, but if the number is already displayed the second method is the only efficient one if you do not want to copy the result on a piece of paper and retype so as to calculate its reciprocal.

- 1 / numerical value or
- use the key sequence [SHIFT] [ ) ] (X to -1), if the number is already displayed (stored in answer Ans memory)

1 [/] 13 [EXE] result is 0.07692307692 or

13 [EXE] to have 13 in Ans memory (displayed) and [SHIFT][ ) ] [X to -1] [EXE].

Hello,

You perform all calculations in complex mode. When you need to convert to angle amplitude, in the [RUN] screen press [OPTN][F3:CMPLX]

To obtain the angle press [Arg] ( complex number) [EXE]

To obtain the magnitude, amplitude press [Abs] (complex number) [EXE].

Since the [ANS] memory keeps only the last value calculated, you may have to store your result (the complex number) in a variable.

1+ 1 i [white right arrow under tan key to store] [ALPHA] H

Display shows 1+1i. Then

[Abs] [ALPHA] H [EXE] gives 1.414213562

[Arg] [ALPHA] H [EXE] gives 45

Hope it helps.
