Hello,

Just so that we know what we are talking about. The natural display is the display mode in which fractions appear on two lines, radicals appear as radicals, log can be calculated in any base, etc. If that is what you understand by Natural Display, we are in agreement.

To set this mode, you turn calculator ON and press [SHIFT][MODE] (setup). The option is called MathIO, and it has the number 1.

Thus [SHIFT][MODE][1:MathIO].

Hope it helps.

SOURCE: Casio fx-7400G PLUS cubic solver?

Hi,

First let us repair the terminology.

- You can evaluate any expression (find the value of any expression for a particular value of its variable).Store a value in the variable, say X. Key in the expression and press [EXE].
- You can consider your expression(should not contain a relational operator such as =, greater than, less than, greater than or equal to, less than or equal to) to be a function Y1(x) = expression and graph it, or generate a table for it. You will have several values of the function calculated at various points.
- You can set your expression equal to 0 and find the particular value(s) of the variable (the unknown) that make the equality TRUE. That is called solving an equation.

Hope it helps.

Thank you for using FixYa and for rating this solution.

SOURCE: how can i calculate log inverse with my fx-991ES

By 'log inverse', you presumably mean the inverse of the logarithm function. There are two logarithm functions on most scientific calculators. Firstly [ln], or natural logarithms, to the base e, where the inverse is e^x. Secondly [log], or logarithms to the base 10, where the inverse is 10^x.

Example 1 : ln(2) = 0.69314718 so e^0.69314718 = 2

Example 2: log(2) = 0.301029995 so 10^0.30102995 = 2

To convert a single answer from symbolic to decimal, press the S--D key (just above the DEL key). To have all answers come out in decimal format, press SHIFT MODE 2 to switch to the LineIO mode.

You can't do that on Casio fx-991es plus calculator. Usually, infinity symbol available in calculators with CAS (Computer Algebra System).

This is a good scientific calculator that can do a lot, but things in the realm of a CAS (Computer Algebra System) are beyond its capabilities.

You should try to explore the calculator to find its capabilities. You can also read the manual. Everything is in it.

Press the Mode button, then the down arrow key. On the second page of the mode list you find**2:Verif**

Sorry, It is not possible to solve equations on the Casio FX-82 ms. Try the Casio FX-115 ES/ FX-115 ES Plus, FX-991ES/ FX-881 ES Plus C.

The FX-991ES Plus barely handles simple operations on matrices of dimensions up to 3X3. It cannot find eigenvalues or eigenvectors.

If it does not have the FACT key, you must factor by hand: Divide by 2, then by 3, 5, 7 etc.

Write your equations first, then try to use the calculator to solve the problem. If you don't know how to do it by hand, you won't be able to ask the calculator to do it for you.

Hi,

If you cannot find it, buy an FX-991ES. It is solar-powerd and it has the natural text-book display, which is a novelty in calculators.

I know that Staples carry the FX-991ES.

Hope it helps.
