Question about Texas Instruments TI-84 Plus Calculator

I need to know how to input numbers into the calculator to solve problems of exponential functions

Re: inputing numbers to solve exponential functions

There is a nice tutorial on prenhall.com

this works for ti 83, 83+, 84, 84+ and 84+ silver

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 1**0^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.

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

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

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.

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.

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).

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.

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

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.

Hello,

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

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!
