Try them by yourself or read the manual. You should be able to figure out most of them.

85-84cos(25 deg)=8.87015 and I do not see how you get 3. If angle is in radians the answer is 1.73896. Make sure your calculator is configured to use the right angle unit (radian, degree or gradian).

The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver.

You cannot use it to solve equations.

Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991.

Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.

The equivalent of the EE or EXP button on the Casio Fx-115ES is marked
as x10^X. It is located at the bottom right of the key pad left of the =
key.

To enter the power of 10 in a number written in scientific notation, you press the x10^X button followed by the exponent. If the exponent is negative you press the change sign key first [(-)] , then the one or 2 digits in the exponent.

Example Enter the mass of the proton m_p in kilograms

**1.6726217 [x10^X] [(-)]27 [=] **

In grams the value above is multiplied by 1000.

or**1.6726217 [x10^X] [(-)]24 [=] **

Since the calculator has the physical constants (the FX-991ES definititely has them)

Since the calculator has the physical constants (the FX-991ES definititely has them)

- Display the proton mass in kilograms
- [SHIFT ][7] to open the constants catalog,
- type 01 for the proton mass, then press the [x^-1].
- Divide the result by 1000
- You should get 5.978638635 x10^23

Your question is slightly ambiguous.

If you refer to the exponential function (power to base e = 2,7182818...), the key sequence is [SHIFT] [ln]. (rightmost button column, two rows below the ON key).

If you refer to a key allowing to enter powers of 10, like in 3,14 x 10²³, see the button labeled

its located in the bottom button row, center column.

General shortcut.

If the concentration is of the form 1* 10^ (-a) where a is an integer between 0 and 14, the pH is given by a.

c= 1.* 10^(-5), pH=5

c=1.*10^(-11(, pH=11.

For other values, ex: c=3.68 *10^(-8)

pH: 3.68 [EXP] [+/-] 8 [LOG] [+/-] Result is 7.434

Above, the [+/-] key is the change sign key, just above the [7] key.

The structure of a number in scientific notation is as follows

one digit [decimal mark] several digits power of 10 (- sign if needed) up to two digits for the exponent.

d.ddddd [10^] (-) dd

To enter a number in scientific notation you need to use the [EXP] key, between the [.] and the [=] sign, on the bottom row of keys.

Ex: Avogadro's number (do not worry if you do not know what it represents)

Na= 6.02 x10 ^23

6.02 [EXP] 23 [=]

Electron charge 1.6 x10 ^(-19)

1.6 [EXP] [+/-] 19 [=]

The [+/-] key is the change sign key, in the first column of keys, between the fraction key [a b/c] and the [7] key

one digit [decimal mark] several digits power of 10 (- sign if needed) up to two digits for the exponent.

This can be done by setting the calculator to the right MODE. Press MODE 9 to turn on scientific notation. For example, compute 1 / 200 = and you will see 5 with a -03 exponent in the upper right. Press MODE 9 again and it will be displayed .005

To enter numbers in scientific notation use the EXP at the bottom. To enter .005, press 5 then EXP then +/- then 3. You will see it displayed. Then you can perform calculations with this entered number.

Hello,

Yes it does. All scientific calculators do logs, power, roots, exponential, trigonometric functions. Most do also hyperbolic and inverse hyperbolic functions.

Hope it helps.
