TI-34
The TI-34 name is a branding used by Texas Instruments for its mid-range scientific calculators aimed at the educational market. The first TI-34 model was introduced in 1987 as a midpoint between the TI-30 series and the TI-35/ TI-36 series. Earlier models included Boolean algebra features, though these were removed with the introduction of the TI-34II in 1999, which focuses more on fractional calculations and other subjects common in middle and high school math and science curricula. TI-34 (1987) The feature sets were similar to TI-36 SOLAR introduced in 1986, but without complex number support, normal distribution stat functions (P(), Q(), R()), permutations, combinations, factorials, user-accessible operand registers. However, it added fraction mode display and conversion (pure/mixed), boolean logic operations (NOT, AND, OR, XOR, XNOR) over contemporary TI-35 PLUS/36 SOLAR. It uses the Toshiba T7988 processor. The key and case design was based on contemporary TI-30 SLR, T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientific Calculator
A scientific calculator is an electronic calculator, either desktop or handheld, designed to perform mathematical operations. They have completely replaced slide rules and are used in both educational and professional settings. In some areas of study scientific calculators have been replaced by graphing calculators and financial calculators which have the capabilities of a scientific calculator along with the capability to graph input data. Functions When scientific calculators were originally marketed they normally had only four of five capabilities (addition, subtraction, multiplication, division and square root). Modern scientific calculators generally have many more capabilities than the original four or five function calculator, and the capabilities differ between manufacturers and models. The capabilities of a modern scientific calculator include: * scientific notation * floating-point decimal arithmetic * logarithmic functions, using both base 10 and base e ...

TI-30
The TI-30 is a scientific calculator manufactured by Texas Instruments, the first model of which was introduced in 1976. While the original TI-30 was discontinued in 1983 after several design revisions, TI maintains the TI-30 designation as a branding for its low and mid-range scientific calculators. Price The original TI-30 was notable for its very low cost for the time, around US$25. This was much less than the retail prices of other scientific calculators of the era; for example, Hewlett-Packard's cheapest scientific calculator at the time was still well over $100. The Casio FX-20, another popular scientific calculator, sold for roughly double the price of the TI-30. The TI-30 sold for less than the cost of a professional-grade slide rule. The TI-30 sold an estimated 15 million units during its lifespan from 1976–1983. Description The original TI-30, a cost-reduced but functionally equivalent version of TI's SR-40 unit, utilized an LED display, is powered by a 9-v ...

Boolean Algebra (logic)
In mathematics and mathematical logic, Boolean algebra is a branch of algebra. It differs from elementary algebra in two ways. First, the values of the variables are the truth values ''true'' and ''false'', usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers. Second, Boolean algebra uses logical operators such as conjunction (''and'') denoted as ∧, disjunction (''or'') denoted as ∨, and the negation (''not'') denoted as ¬. Elementary algebra, on the other hand, uses arithmetic operators such as addition, multiplication, subtraction and division. So Boolean algebra is a formal way of describing logical operations, in the same way that elementary algebra describes numerical operations. Boolean algebra was introduced by George Boole in his first book ''The Mathematical Analysis of Logic'' (1847), and set forth more fully in his '' An Investigation of the Laws of Thought'' (1854). According to Huntington, the term "Boolean algebra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Complex Number
In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted , called the imaginary unit and satisfying the equation i^= -1; every complex number can be expressed in the form a + bi, where and are real numbers. Because no real number satisfies the above equation, was called an imaginary number by René Descartes. For the complex number a+bi, is called the , and is called the . The set of complex numbers is denoted by either of the symbols \mathbb C or . Despite the historical nomenclature "imaginary", complex numbers are regarded in the mathematical sciences as just as "real" as the real numbers and are fundamental in many aspects of the scientific description of the natural world. Complex numbers allow solutions to all polynomial equations, even those that have no solutions in real numbers. More precisely, the fundamental theorem of algebra asserts that every non-constant polynomial equation with re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Projector
An overhead projector (often abbreviated to OHP), like a film or slide projector, uses light to project an enlarged image on a screen, allowing the view of a small document or picture to be shared with a large audience. In the overhead projector, the source of the image is a page-sized sheet of transparent plastic film (also known as "foils" or " transparencies") with the image to be projected either printed or hand-written/drawn. These are placed on the glass platen of the projector, which has a light source below it and a projecting mirror and lens assembly above it (hence, "overhead"). They were widely used in education and business before the advent of video projectors. Optical system An overhead projector works on the same principle as a slide projector, in which a focusing lens projects light from an illuminated slide onto a projection screen where a real image is formed. However some differences are necessitated by the much larger size of the transparencies used (g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
