Question about Texas Instruments TI-83 Plus Calculator

Hello,

Unlike other, less sophisticated calculators, the TI83Plus /TI84Plus /TI84Plus Silver Edition do not have a simple key or a command for improper fractions. However there is a command -->Frac accessible through **[MATH] key [1:-->Frac]** that expresses a result in a proper fraction format.

Here is how you would enter you calculation

3+ 1/2 +4+1/8 [MATH][1:-->Frac][ENTER] result is 61/8

You can also ease a bit on the typing by mentally adding 3 and 4

7+ 1/2 +1/8 [MATH][1:--Frac][ENTER]

You should know about the other command that converts a fraction in decimal format. **[MATH][2:-->Dec][ENTER] **

If you enter this command just after the one handled above, your screen shows [Ans][-->Dec] on one line and the result 7.625 on the next. If you do not enter a number the calculator uses the last CALCULATED result, which is stored in the system variable [Ans]

Hope it helps

Your best bet would be trying a math package on ti-calc.org - you can usually find something that does what you want there. You'll need a cable and the software to download these programs to your calculator. Here's a link to the trig section:

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

The calculator is a very advanced one. It has hundreds of commands, each doing something different. Do you honestly think that anybody, no matter how well intentioned, can possibly give you step by step instruction on how to operate the calculator? And for free.

TI publishes just such a guide book.**It is freely available on their website at education.ti.com.** Download the complete guide book, browse through it to look for the way to solve the problem you are studying. Be focused. Read only what you need, to solve the problem at hand.

However, if you have a more specific question such as how do add two numbers, how do I find the inverse of a matrix, or anything with limited scope, we will be happy to answer it.

Please formulate a question.

That is the correct answer. 60 multiplied by 24 is 1440. 1400 divided by 1440 is a number slightly smaller than 1.

Are you sure the problem isn't 1440/(60*24)?

Are you sure the problem isn't 1440/(60*24)?

When you use trigonometric functions you should always make certain that the angle unit the calculator is configured for is the intended one.

When the unit is set to degree sin(37)=0.6018

When the angle unit is set to radian, sin(37 rad)=-0.6435

Change the angle unit to degree.

When the unit is set to degree sin(37)=0.6018

When the angle unit is set to radian, sin(37 rad)=-0.6435

Change the angle unit to degree.

- Press the MODE button
- Scroll to reach the Angle line.
- Use right arrow to highlight deg and press ENTER to validate.

just type it in, e.g. 1/2 or 3/5.
if you want to have answers display as fractions, press [MATH] ENTER.

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.

(I know this because I have a TI-83 calculator)

this could be an assymtote and if you really want exact answers use the table function or just press trace and type in an x value

I reccently had the same problem, but I have a Ti-84 Plus,and I am disgusted by how poorly this matter is covered by Texas Intruments. Esp. since the solution is rather simple.

The antilog key is [2nd] [log] or the 10^x. On your screen it should apear as 10^( and then you just input the value that you want to find the antilog of.

When used to solve pH problems remember to input the pH value as a negative number, since pH= -log[H+] then [H+]= antilog(-pH).

Hope that helped))))) ^^
