20 Most Recent Casio FX-250HC Calculator Questions & Answers

The common antilog of 250 is 10^250 (a one followed by 250 zeroes). The natural antilog of 250 is about 3.75*10^108.

écoute, ne te fâche pas : je ne comprends pas le sens de ta question et je devrais m'abstenir de te venir en aide, craignant d'interpréter incorrectement ton problème (et ce n'est pas ma maîtrise de la langue de Molière qui est en faute!!) Mais je vais quand même essayer de t'aider.

L'indicateur DEG que tu sembles vouloir éradiquer est parfaitement inoffensif. It est affiché sur l'écran pour te rappeler que l'unité d'angle est le degré. Cela signifie que tout argument que tu fournis à une fonction trigonométrique (sinus, cosinus, tangente, cotangente) est interprété comme une valeur en degrés. Donc si tu calcules sin(Pi) ne t'attends pas à obtenir 0 mais le sinus de 3,14.. degrés.

De même, toute valeur retournée par une fonction trigonométrique inverse ( arc sinus, arc cosinus, arc tangente, arc cotangente) sera en degrés.

Si tu changes l'unité d'angle de degré à radian, l'indicateur RAD sera affiché quelque part sur l'écran. Donc je te suggère de ne pas t'acharner à faire disparaître cet indicateur: Il ne fait que te monter quell unité d'angle tes calculs utilisent. C'est plutôt commode, ne trouves-tu pas?

Maintenant, si tu veux préciser ce qu'est ce reste que tu cherches, peut-être pourrais-je t'aider? Tu n'as qu'à faire un commentaire et je verrai ce que je peux faire.

Use x^y, which is the shifted function of the multiply key. For example, to raise two to the tenth power, press 2 SHIFT [x^y] 1 0 = .

Look for a key marked as [a b/c]To use it to enter an (improper) fraction type in the numerator , press the [a b/c] key the type in the denominator thaen press [=].To enter a mixed number type in the integer press [a b/c] thype in the numerator, press [a b/c] then type in the denominator followed by the =/EXE key. the result will be displayed as [integer number] [r] [numerator] [r] [denominator]. The separator [r] may look that the letter r or the letter u.

The fx-250HC uses two standard AA batteries. You may use either rechargeables or disposables, but make sure the two batteries are of the same type and vintage.

Change the mode then. The default is the COMP or general computational mode. Read the manual to understand how to change modes, or take the time to specify which mode you want to get out of.

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.

While it may have many of the same functions as a graphing calculator. It cannot produce a graph on the screen. This is required for most classes. It is not considered a graphing calculator, and you will most likely have to buy a new one.

The calculator doesn't have those functions built-in. Use the relationships sec(x) = 1/cos(x), csc(x) = 1/sin(x), and cot(x) = 1/tan(x).

Use the x^-1 key, second row, far left. 1/x is x to the -1 power.
