Calculators

brainstom

zybez.net should have one, check the sidebar on the left.

Go to the y= button, and type in your equation by the y1 (if there's 2 equations, press enter and type the 2nd one in by the y2). Then press graph.

press 4

A scientific calculator.

-2

change it to polar mode and then plot r = any constant

example output of c++ calculator

There is a button above the division sign that looks like this: ^

You type: 2^5 which means 25

x-3x=9

A number times itslef (n^2, or n x n).

A good rule of thumb is to only use slide transitions that you have heard of from the movie industry such as cut or fade. Then only change them when you have a major change in theme. Such as Part 1 and Part 2 would feature only two transition types -one for each part.

A computer can perform many functions beyond a calculator, including advanced calculations as well as communication, graphics and other high-level activities.

In terms of what?

a person invented it. i do abid you a good day now.

The scientific notation for 670616640 is 6.7061664 × 108

You cannot change the language. However, many Texas Instruments provides alternatives to included applications in different languages. Unfortunately, outside of TI's applications, there are very few programs written for languages other than English.

what u do is as someone very smart to do it for you

Alcohol is a drug that enters the bloodstream without being broken down in the stomach by the digestive system. Therefore alcohol gets to the brain quickly (unless there is enough food in the stomach to slow it down). When an alcoholic beverage is swallowed, it is diluted by gastric juices in the stomach. A small portion of the alcohol is diffused into the bloodstream directly from the stomach wall, but most passes through the pyloric junction into the small intestine, where it is very rapidly absorbed. However, up to half the alcohol is degraded in the stomach before it passes into the small intestine. In general, a lower percentage of the alcohol is degraded in a young woman's stomach than in a young man's because a young woman's gastric secretions contain lower levels of the enzyme alcohol dehydrogenase (ADH), which breaks down alcohol prior to absorption. The rate at which alcohol is absorbed can be affected by a number of factors. For example, a strong alcoholic drink, when taken into an empty stomach, may cause a spasm of the pylorus that will impede passage into the small intestine, resulting in a slower overall rate of absorption. The presence of food in the stomach, especially some fatty foods, will also delay absorption. Naturally carbonated alcohol such as champagne or alcohol taken with a carbonated beverage such as soda water will ordinarily be absorbed more rapidly than noncarbonated alcohol. Other factors, such as the emotional state of the drinker, may also affect the rate of absorption. *just a reminder that the amount of alcohol degraded in the stomach via gastric ADH is usually lower than the main organ of degradation via ADH, the liver. Gastric ADH is found within the stomach cells and not in gastric secretions. So ADH in fact mostly breaks down alcohol AFTER it's been absorbed, not before*

In order to find the log with a power of ten, use the LOG button. For example, to find log105, type log(5). (The parenthesis after the g will appear when you press the LOG button.

In order to find a log with a power other than ten, you will have to divide by the log10 of that power. For example, to find log82, type log(8)/log(2).

In order to find the natural log of a number, use the LN key. For example, to find the natural log of 91, type ln(91).

youcan get a specific type like the TI-34 (MOST BEST) but you can get a random one mostley i get all of my school suplies @ staples ( WHARE I GOT THE TI-34)

For example, if you want to find the least common multiple of 17 and 256:

Press Math and select NUM at the top with the arrow keys. Scroll down and choose the option that says lcm(. Then type the first number, followed by a comma, followed by the second number. Put in an ending parenthesis (If you don't, it will still work, but this is good practice for when you get to more complex problems.) You should see:

lcm(17,256)

Press ENTER. In this case, the answer will be 4352.

Hit the second button, it allows all the keys on the TI-83 to have a second function.

Now, hit the plus button. There should be a MEM on top of it, this stands for memory.

Now scroll down using the arrow keys to the 7th option, which says reset.

It will confirm that you want to clear the RAM. Then press YES.

Your TI-83 plus is reset.

The first calculator ever made cost about $2500, compared to the $12 it costs now.

i hope this helps you!

An abacus?

The abacus is the first true precursor to the adding machines and computers which would follow. It worked somewhat like this:

The value assigned to each pebble (or bead, shell, or stick) is determined not by its shape but by its position: one pebble on a particular line or one bead on a particular wire has the value of 1; two together have the value of 2. A pebble on the next line, however, might have the value of 10, and a pebble on the third line would have the value of 100. Therefore, three properly placed pebbles--two with values of 1 and one with the value of 10--could signify 12, and the addition of a fourth pebble with the value of 100 could signify 112, using a place-value notational system with multiples of 10.

Thus, the abacus works on the principle of place-value notation: the location of the bead determines its value. In this way, relatively few beads are required to depict large numbers. The beads are counted, or given numerical values, by shifting them in one direction. The values are erased (freeing the counters for reuse) by shifting the beads in the other direction. An abacus is really a memory aid for the user making mental calculations, as opposed to the true mechanical calculating machines which were still to come.
