Question about Casio CFX 9850GA Plus Calculator

Hello,

There is no key dedicated to **e, **the base of natural logarithm, the same as there is for pi. However you can find it as the VALUE of the exponential function e^(x) for x=1. To obtain the VALUE of **e** you press [SHIFT] [ln] to access e^x, enter 1 and press [EXE].

Thus

[SHIFT][LN]1 [EXE] gives 2.718281828.

If you need that numerical VALUE often you may want to store it into a variable, say E. To do that

[SHIFT][LN]1 [-->] [APLHA] E [EXE]

From experience, I know that it is not the VALUE of **e** that you need but the symbol **e** to define the exponential function. If you press [SHIFT][LN] you get a syntax error. You can never see **e **in a multiplication, addition, or other arithmetic operation.

In this calculator, the** e **is first and foremost the symbol for the exponential function. If you need to draw the exponential function of X

you press [SHIFT][LN] X. Parentheses are not needed for simple arguments as this one, but if the exponent is a complicated expression parentheses are needed.

If you mean exponential of X you type [SHIFT][LN] [X,theta,T], but if you want exponential of (x-3z+ 0.5 y^2), you must enclose the argument (the object of the function) between parentheses

[SHIFT][LN] [ ( ] x-3*z+ 0.5*y [^]2 [ ) ] [EXE].

Hope it helps.

There isn't one. You can calculate e by raising e to the first power. Press 2nd [e^x] 1 ) =

Many things are named after Leonhard Euler and that includes the base of natural logarithms (e=2.7.....)

To use the constant itself you must use e^(1) or enter exponential of 1. A few calculators have a specific key to enter the constant e as for Pi, but most do not and that is why you must use e(1).

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.

your model isn't listed, but read rules Calculators are only allowed to be used on the mathematics test; however, a calculator is not necessary to take the exam. Any student who attempts to use a calculator on the science exam will be dismissed and the worksheet will not be scored. It is the student's responsibility to make sure they bring sufficient batteries and that the calculator works properly. Test center personnel do not have backup calculators or batteries.
Only certain types of calculators may be used during the test. Most four-function, scientific or graphing calculators are permitted, but some features may have to be disabled before the calculator can be used. Devices that include calculators among their functions-cell phones, laptops, PDAs-are forbidden, as are calculators with built-in algebra capabilities or QWERTY keyboard buttons. Also, certain specific models of calculators are forbidden, including the following: all Texas Instruments model numbers that begin with TI-89 and TI-92, as well as the TI-Nspire CAS (the non-CAS TI-Nspire is allowed); the Hewlett-Packard hp 48GII model and all model numbers that begin with hp 40G, hp 49G, or hp 50G; the Casio Algebra fx 2.0, ClassPad 300, and all model numbers that begin with CFX-9970G; and all electronic writing pads or pen-input devices, except for the Sharp EL 9600.

As mentioned previously, certain calculators can be used after extra features are disabled. Calculators that use paper tape, for example, may be used after the tape roll is removed. If the student has a model that makes sounds, disabling the sound feature makes the calculator acceptable for use during the test. For calculators that can communicate wirelessly, infrared ports must be covered with opaque material (such as electrician's tape or duct tape) of sufficient thickness to block infrared signals; the Hewlett-Packard hp-38G and hp-48G series are examples of this device type. Also, calculators with power cords must have the cords removed before they can be used during the exam.

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.

The exponential function and the natural logarithm (LN) are inverse of one another. They share the same physical key. To calculate the natural log [LN] press the key marked LN and enter the number. Close the parenthesis) and press [=]

To calculate the exponential, use the key combination [SHIFT][LN] followed by the number.
