Question about Texas Instruments TI-84 Plus Calculator

Re: eValueate feature

I'm just guessing (i don't know but this is my best guess) it's an aplication. try under the APPS button. above the sin and button. and look under there. HOPE this helps. sorry if it doesn't there's a good chance it won't GOOD LUCK.

To evaluate the expression you need the value of x.

To solve you do as follows

ln(5x)=12/4=3

Take the exponential of both sides of ln(5x)=3

e^(ln(5x))=5x=e^(3)

This gives**x=(1/5) e^(3)**

To solve you do as follows

ln(5x)=12/4=3

Take the exponential of both sides of ln(5x)=3

e^(ln(5x))=5x=e^(3)

This gives

-343. If you'd like to know how to evaluate this on a particular calculator, please specify the make and model.

4/sqroot2 is the same value as 2sqroot2, about 2.828 . It's just a matter of how the calculator and the textbook chooses to represent the value.

Hi

if you can open the calc and check if you see some spots of liquid or acid that leak from the batter if yes take the main circuit out and clean the contact if it will not help its an hardware failure

this can be fixed let me know if you want to fix

Evaluate it by pressing

5 . 8 * SHIFT ln ( . 5 6 * 4 ) =

You don't need to enter "e". Just use the e^x function (the shifted function of the ln key).

The order of evaluation is fixed. You can override this order in an expression by using parenthesis. For example, 3+4*5 is evaluated by multiplying 4 by 5 and then adding 3. If you want to do the addition first, you can enter it as ( 3 + 4 ) * 5 .

The order of evaluation is given in the "Equation Operating System" section of Chapter 1 of the manual.

Divide 139 by 152, then multiply by 100.

Sorry, but that feature is not implemented on the TI84 family of calculators. No key or command will instruct the calculator to perform such a calculation.

You may deplore such a shortcoming, but please, do not hold me responsible for it.

Enter any fraction as a division problem and your TI 83 will evaluate it as a fraction.

For instance, 3/4 = three fourths.

Hello,

You should know that you cannot enter something like sin^2(x) as you would by hand. So you must use parentheses:**( sin(x) )^2. **If you do that there is no ambiguity. The calculator evaluates the sine because parentheses are evaluated first, then it takes the square.

So 4[x]**[(]** [SIN]*[(] *60 *[)]* **[)] **[Xto the 2] [=] result is 3/

Since you do not say what model you use, what I entered may not be appropriate: the parentheses inside the sine function may not be needed. In the new Casio the first parenthesis inside the sine is supplied by calculator, but the closing one must be entered by the user.

Hope it helps
