Is there a difference between TI-89 Titanium calculator and TI-83 calculator?
Because I'm taking a final exam and my teacher will only allow us to use a TI-83 calculator and
I've never used it... like for putting in the parentheses with the log when dividing log4-log7 / log6... Is log the same as ln because I tried using it on my friend's calculator and it gave the wrong answer.
Would I put it in as ((log(4)-log(7))/((log(6)) ?
Also my teacher said that if we want to keep the answer from a problem to use in another problem I needed to use something to save the whole number (for example when the number is 0.85694...). An example would be finding the half life of something (finding the growth or decay factor (the k) in the equation y=ne^kt) and then putting the answer found for k into another equation.
Does anyone know what I need to do on the TI-83 calculator???
Thanks, and also can someone answer this and not put a website?
Is TI-83 a graphing calculator? Because if it is then the teacher will not let me use the TI-83 either. Is there another caculator with the log and ln, square root...? Is it the TI Scientific Calculator that does not have graphing? Because the TI Scientific Calculator is the one that my friend had, and I had trouble with it? If so, could someone answer the questions above for the TI Scientific Calculator? Thank You
Also is there a website with the online TI Scientific Calculator so I can practice?
Thanks
how do you put 6^2/3*6^2/3 in a calculator or how you put fractions in
ln 3000000-ln500/6
Yes, there are differences between the TI-89 Titanium calculator and the TI-83 calculator. The TI-89 Titanium is a more advanced graphing calculator with additional features compared to the TI-83. However, for your final exam, your teacher specifically requires the TI-83 calculator, so let's address your questions accordingly.
To input an expression involving logarithms on the TI-83 calculator, you use the LOG function instead of log or ln. For example, to calculate ((log(4)-log(7))/(log(6))), you would input ((log(4)-log(7)))/(log(6)).
On the TI-83 calculator, the LOG function computes the common logarithm (base 10), whereas the natural logarithm (base e) can be calculated using the LN function. So, if you were looking for the natural logarithm, you would instead use ((ln(4)-ln(7)))/(ln(6)).
Regarding saving a result for later use, the TI-83 calculator does not have built-in functionality to save values directly. However, you can store intermediate results in variables. For example, if you want to save the value 0.85694, you can assign it to a variable using the STO> function. This can be done by typing 0.85694, then pressing the STO> button, followed by the variable name you want to assign it to (e.g., A). The value will be stored in variable A, and you can recall it later by simply typing A in your subsequent calculations.
Remember, it's important to review your calculator's manual or seek additional resources to familiarize yourself with button functionalities and their corresponding symbols on the TI-83 calculator. Good luck with your exam!
