# How to use ti 86

input variable if you intend to draw the graph of the equation or use the TI table. We illustrate graphing using the equation in Example 3 of Section v(t) = (t). Press GRAPH F1 [y(x)=] to access the graphing list. If there are any previously entered equations that you will no longer use, delete them from the graphing list with F4 [DELf]. To clear, but not delete, the location of an equation. Solution The TI calculator reads v 4? as p (4 ? ?). = because it uses Rule 8 and multiplies the 4 and the ? before taking the square root. Enter (v 4)? or v 4? ? instead to obtain the correct value The TI yields (v 4)? = 2?. = , as expected, because it does not use Rule lovesdatme.com Size: KB.

This is a bit of a pain, as you have to be careful to use the [ALPHA] key for uppercase and [2nd][alpha] keys for lowercase. But the payoff will be worth the trouble, because once these equations are in your calculator, you will not have to enter them again for the life of the calculator.

Note that we use 'mol' instead of 'n' in the ideal gas law because 'n' is not allowed as a variable on some calculators. In addition, we use "d" instead of just because "d" is easier to enter from the keyboard. Entering Equations To get started with the TI, first enter the solver. Note that we use 'mol' instead of 'n' in the ideal gas law because 'n' might be used for all sorts of other meanings in other equations. Press [MORE] if you don't see it.

Don't forget [2nd][RCL]! If you forget these strokes, you can solve the equation, but you can't see what you're solving! The default upper bound is not large enough for many of our problems.

A value of 1E99 should be fine. Solving Equations After loading the equation into the solver, you should how to use ti 86 something like the following. The heading "eqn:" does not show on the TI Some of these variables may have numbers after them, depending upon what already may be defined in your calculator. The values will persist even after the calculator is turned off. Clear out the equation and load it again.

Let's solve the following problem: What is the volume how to use ti 86 1. Enter the values of all of the variables you know. You have to think about precision and do the rounding off yourself. On homework and exams you probably won't get full credit if you answer " Math in the Solver You can do math as you define how to use ti 86 variables. For example, say you were given that the temperature was 15 o C. You could add "on the fly": What is the volume of 1.

Or maybe you want to solve for pressure, and the value you need is torr. For example, What is the partial pressure in torr of 1. Note that we use three significant digits, because the temperature in Kelvin is By adding to 25, we increase the precision of the value.

Editing and Saving Equations If you find you need to edit an equation, here's how you can do it quickly. First set it up exactly the way you want by editing the first line of the solver. Test it out to make sure it does just what you want it to do.

This equation is now stored in the variable 'eqn'. Exit the solver. We're just going to define 'IDEAL' to be the value of the variable 'eqn', from the top line of the solver. Just use the solver to get the equation the way you want it. Test it out how to use ti 86 make sure it does what you want it to. Editing and Saving Equations Just use the solver to get the equation the way you want it.

Then, for the TI, while in the solver, save the equation by pressing [F1] 2 [downarrow] and entering the name you want to give the equation. Deleting Equations On the TI or TI, the easiest way to delete an equation is to turn it into a simple variable by storing the value how to make wooden boat in it. Scroll down to the equation you want to delete and press [F1] 1. Using Variables Outside the Solver The variables you define using the solver are still there after you exit the solver.

Just use them like any other variable: 'x' is x, 'P' is P, 'dG' is dG, etc. Constants Several constants come with your calculator as "built-in" values and can be used in any calculation or equation.

Here are some of the more useful ones for chemistry: Constant. How to draw realistic puppies step by step Built-in constants are not worth their trouble on the TI However and this is a BIG howeverthey are returned with units. The capability of manipulating units is a feature of the TI that is unique to it.

While this might sound useful, there are two serious practical problems using this feature on the TI This is just incredibly time consuming. Second, the constants with their units cannot be used in the numeric solver. Since we will be making much use of the numeric solver, we suggest you igore the built-in constants how to paint and distress metal your TI Instead, simply take the time now to enter the constants listed above into your calculator.

For example: 6. Conversion Factors By pressing [2nd][CONV] you will find quite a few useful conversion factors, including those shown below. Press [MORE] to see additional categories how to download music onto computer more conversions in each case. Conversion Factors The TI does have conversion factors, but they are not useful in practice.

The problem is that a they are annoyingly difficult to find and b once again, they require all numbers to be entered carefully with units.

There is an upgrade set of programs avaialable from TI which is supposed to give the TI the capabilities of the TI for statistics. I have not yet had the opportunity to try it out. There are three situations in which you enter data - one variable actual data , one variable with frequencies grouped or ungrouped , two variable. In the TI, you always have to indicate frequencies, even if they are all 1's. Always clear old data before entering new data, or your results will be messed up:.

You must also enter a list of values in the list "fStat" - these will all be 1's. The list must be the same length as your list of values. The frequencies number of times repeated for the values are entered in the list fStat - there must be a frequency for each value.

Values go in pairs : x values in first column headed xStat y-values in second column yStat easiest to enter all x-values down the xStat column, then y-values down the yStat column, next to corresponding x-values.

You cannot calculate with the data table showing - you must return to the home screen by pressing "Exit" if you are looking at the data.

Note: to save the regression equation for graphing, you add to the regression command. You can, of course, use any other function name in place of y1. The TI will produce boxplots, modified box plots, or histograms from one-variable data, and scatter plots from 2-variable data. Up to three plots can be defined at one time. The one variable types are "Box" for basic boxplot, "MBox" for modified boxplot dots for outliers "Hist" for histogram.

The two variable types are "Scat" for scatterplot the more useful and "xyline" for a scatterplot with the points connected in the order they appear in the list - not generally useful unless the x-varaible represents time or order and the list is in order.

Cursor down. If you define and turn on a scatterplot and calculate the regression line with the same data using the command that saves the line to y1 the line will appear on the plot when you give the "graph" command. Errors or questions? Please let me know: cpeltier saintmarys.
