Not if the backup battery's good---that's what it's there for. You may not be able to read the screen afterward, TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. If this happens, turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Save equation fx 991es


In table Mode you can enter the formula for a function and generate a table of values. For a 991ES Plus you can enter two functions. However if you change MODE everything will be erased.
In EQN (equation) there is a certain number of built in formula types you can choose. You will be asked for the coefficients which will be used to solve the equation selected. However if you change MODE your lose what you entered. So basically you cannot save formulas to use as a memory aid (if that is what your intention is.) Sorry.

There's something wrong with my TI-83. When I'm typing up an equation it will randomly shut off. And when it's on it will have shown that the RAM was cleared. Now it sometimes takes like 5 presses of the...


Have you tried changing the batteries? I'd try that first thing. From your description, the problem sounds like you have low batteries. The RAM shouldn't clear itself when you turn the calculator on unless you tried to turn it on when the calculator didn't have any juice. The TI-83 has four AAA batteries and one CR1616 battery it uses for memory backup. The CR1616 isn't enough to power the calculator, just enough to keep your calculator from losing its RAM contents while the primary batteries are out. If you try to power the calculator on without primary batteries, the backup fails. However, the TI-8x line is usually pretty good about warning you when the batteries are low by displaying a big warning message when you turn it on about the batteries being low and a recommended change of batteries. It might not, though, so you really can't be sure until you try a fresh set of batteries. Good luck!

Garmin c340 loses the satellite very frequently. Battery?


1. make sure the unit is as low un the windshield as possible, remember it needs to see the sky, the more sky it can see the more sat it can lock in on.
2. Check the GPS Mode, under tools(Wrench), select system, the GPS mode, make sure it is in the normal setting. WAAS is more accurate, but most of the sats are at the equator, so in some areas the coverage is not as good.
Hope this helps.

Problem using graphing on my casio


This calculator has so many options you can change, that it is possible one of them has been altered. Try pressing the master reset button at the back to re-set the calculator. Note that you will lose all your programs and data, so first copy out anything important. Also, set the xmin and xmax parameters to a higher value. To plot a sign wave, try xmin=-720, xmax=720, step=1, ymin=-1, ymax=1, step=.1 The step value won't change the appearance of the graph, just make it more chunky or fine. Use the equation y=sin x. This should draw a sign wave showing 4 complete waves. PS when you enter the X in the equations, you are pressing the X,0,T button, the one under the alpha key, aren't you? If you enter X using the x alpha key, it won't work. Also, to plot y=, make sure you change the func type parameter in the Set Up menu to y=. Hope this helps.

Excel formula.....


Let's start with the 1st equation. I assume you want to be able to recalculate by changing the number of pages.

Put 65 in cell a1.
360 in b1
In C1, put the formula =a1/b1 that's your book thickness
In D1, put .02 for the cover
In E1, put the formula =C1+D1

Now you can change A1, B1,or D1 and the Total thickness gets recalculated automatically. Be careful not to type numbers into C1 or E1, or you lose the formula.

The same for the other equations - a cell for each number ("variable") and another cell for calculations.

Once you've verified the results, then you can get fancy and add titles above each field to make it easy to remember what goes where.

You may need to change the cell format to control the number of decimal places, or thousands commas. Right click on a cell and select format to see the choices you have.

Keep a backup copy of the spreadsheet in case someone (not you, of course) makes a mistake and overwrites the formula cells. You can also look into "protecting" cells to keep them from being changed.

Hope that helps.

Processor FSB


no, the proc will lose speed. the FSB is a part of the equation that determines the processors speed. A lower FSB speed will mean reduced performance.
