Find antilog on es991

The natural logarithm function, denoted ln(x) has an inverse function called the exponential function, denoted e^x. That is what you call the antilog (I prefer the euphony of the exponential).
On calculators the two functions share the same physical key: One function is accessed directly and the other indirectly (SHIFT, 2nd F, or 2nd)
On the Casio FX-991ES the function ln and e key is the the one above the tan key.


The common logarithm or logarithm in base 10, denoted log(x) has an inverse function, the power function in base 10 or 10^x. In your terminology this would also be an antilogarithm.
The common log is accessed by pressing the log key to the left of the ln key, and the 10^x function is obtained with the sequence [SHIFT][log]


Note: The Input/output mode in the foregoing screen displays is the MathIO mode.

Exponential functions logarithm

You're missing a parentheses.

If you mean e^(ln(177/149)/7)*26 then press
2ND [e^x] ( LN ( 1 7 7 / 1 4 9 ) / 7 ) right-arrow * 2 6 ENTER
if you're in the MATHPRINT mode. In the CLASSIC mode press
2ND [e^x] LN 1 7 7 / 1 4 9 ) / 7 ) * 2 6 ENTER

E^ won't work

You are not using it correctly. To calculate the exponential of a number you use the key sequence [SHIFT][LN] to access the exponential function. Then type it the exponent (positive or negative) and close the parenthesis.
You do not use the power key (^)
The exponential function is not affected by the angle unit when you are using real values.

I have a Texas Instruments TI-84 plus silver edition calculator, and I need to know if it has a exponent key?

If you want to raise a number to another, use the ^ key located just above the divide key.
For natural antilogarithm (exponentiation of e), use 2ND [e^x] (the shifted function of the LN key).
For common antilogarithm (exponentiation of 10), use 2ND [10^x] (the shifted function of the LOG key).
To enter a decimal exponent as part of a number, use 2ND [EE] (the shifted function of the comma key, located just above the 7 key.

How to put in a = sign in my problem

The = sign will not always show on the calculator it will depend on what type of problem you are solving.
For numeric problems an = sign will come after the problem is input and the answer will display.
For algebraic or function problems you can input an = sign in the middle of the problem. An example
may be that you input a function. You would input a function by typing in f(x) = 5x + 2 (for example).

What key do I need to press to put in expontenial and logarithmic functions?

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.

To Guru K24674 Hello I have corrected the problem I had, you see the domain function that I have commented about does work within the calculator. You input the domain of the function after the Function...

Here is a solution.

Graph the function over the domain [-Pi,+Pi]
Then press the [SHIFT][MENU] (SETUP) and in option [Dual Screen] select [G to T] Graph to table. The screen will be spilt in two, but the Table part remains empty.
Press [SHIFT][F1] (TRACE), the cross hair appears on screen.
Move it around on the curve
If you press [EXE] at a cross hair location, the table records the X and Y value. On the following screen capture, the exponential function is graphed along with sin(X) and the table is populated by selected values of the exponential.


Now rate all the solutions I provided for you

Is it possible to get euler's number on this calculator? I am a college algebra student starting exponential functions and need euler's number to computer continuous compound interest. Thank you.

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].

[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.

Does the fx-260 SOLAR do exponential calculations?

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

Need Help Solving Exponential Functions ASAP!!!!

You can calculate =4^1.2 in Excel and get 5.278031643
And also in Excel you can determine what the square root of 2 is (2.506628274631) and then in Excel = 5 ^ 2.506628274631 = 56.5012395907155.

I know this is late but maybe it will help later. Assuming I am doing it right. Thanks!
