What is Calculator: Definition and 516 Discussions
An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics.
The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom. They later became used commonly within the petroleum industry (oil and gas).
Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. They became popular in the mid-1970s as the incorporation of integrated circuits reduced their size and cost. By the end of that decade, prices had dropped to the point where a basic calculator was affordable to most and they became common in schools.
Computer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and calculator functions are included in almost all personal digital assistant (PDA) type devices, the exceptions being a few dedicated address book and dictionary devices.
In addition to general purpose calculators, there are those designed for specific markets. For example, there are scientific calculators which include trigonometric and statistical calculations. Some calculators even have the ability to do computer algebra. Graphing calculators can be used to graph functions defined on the real line, or higher-dimensional Euclidean space. As of 2016, basic calculators cost little, but scientific and graphing models tend to cost more.
In 1986, calculators still represented an estimated 41% of the world's general-purpose hardware capacity to compute information. By 2007, this had diminished to less than 0.05%.
Hey there, I'm new to this forum, but I just wanted to let you know that I have put out a clebsch-gordan calculator that is a little bit better than the ones I've found out there so far, check it out. http://phys.csuchico.edu/C-G/

im trying to remember how to do some trig.
first of all, how do you find cos^-1 (5/3) without using a calculator?
2nd, i need help proving this identity:
2sin^2(x) - cos (x) - 2 sin (x) + 1 = 0
3rd, how do you evaluate sin 165 (which is sin (11/12 pi)) again without using a...
Hi, this should be the last question for today :lol:
Determine the number of solutions for the following system:
y = -4log_{12} (x)
y = 4 sin(x)
Is there a way to do this without using a graphing calculator? Thank you very much!
I'm learning physics, and I'm reviewing over the trig part of the chapter. My professor does not allow us to use calculators. I'm looking at the inverse of the trig functions. What I don't understand is : it says that the reciprocal does not equal the inverse. like tan -1 does not equal 1/tan...
take any number, for example X and try and square it...
first let Y = X rounded up the nearest power, not multiple, of 10

I'm not exactly sure if this goes here, but it has a little to do with Academics. I am entering Senior year of HS and I am taking an AP Calc class. Since my TI-83 was stolen, I now have to invest once again into a calculator. As a pre-college student planning on taking many math/science classes...
Hi , I'm entering college this fall majoring in mechanical engineering and I need a graphing calculator. However , I am unsure of which one to buy. These calculators are quite costly so I want to be sure that I am getting the right one. I simply want a calculator that will be able to function...
At the university I'm taking my physics bachelor, only these calculators are allowed on exams:
Casio FX-82

Hi everybody,
I have given an equation to calculate the final Value (FV) of an investment as follows:
FV= Principal*(1+{R/N})^{NT}

When you punch in log on your calculator, mathematically, how is it solving for x?
For example,

How is this being solved?
Thanks

I'm having some trouble solving inequalities with the TI-89. Let's say that I want to solve x^2<1 The answer should be <-1,1>, if I type in solve(x^2<1,x), but that's not what I get. It only returns the inequality itself just as I typed in. What's wrong??
