The Defining Features and Importance of Scientific Calculators By David H. Urmann At Isnare.com Ezine Articles

Scientific calculators are set apart from standard calculators. It has so many functions and features not seen in standard devices. It is very useful to students and businessmen.

A scientific calculator is primarily used in solving problems in physics, engineering, math and science. It has special features that make computations much easier. Some of these are the floating point in arithmetic, functions in trigonometry, exponents and roots, scientific notation, and easy access to constants including E and pi.

The high-end models have features of statistics and probability calculations, equation solving, programmability, fractions, complex numbers, and hexadecimal binary and octal calculations, which comprises of basic Boolean math.

Uses of Scientific Calculators
The uses of scientific calculators are best seen in various aspects and situations. It is time consuming to look for functions on a logarithmic table, as compared to scientific calculator which can readily access certain mathematical functions like the trigonometric functions in a speedy manner. The calculator is needed to calculate problems in Chemistry, Astronomy and Physics involving very large numbers.

Here are some of the common models in the market:

HP 35s Scientific Calculator
The Hewlett Packard (HP) 35s Scientific Calculator is a heavy duty and affordable calculator. It features over 100 built-in functions and work on a 30 KB memory along with 800+ registers. The HP Scientific Calculator also includes 2-line display, indicators and 14 characters.

The other features are power off memory protection, with prompts and menus, 15 digits internal precision, with 13maximum level of pending operation, and Reverse Polish Notation (RPN) and algebraic entry system.

The HP unit is enclosed by a plastic, metal faceplate and has an alpha numeric keyboard. It uses 2 x CR2032 batteries included in the calculator and such battery has a life of about nine months. It measures 3.23 x 6.22 x 0.72 inches and weighs 4.4 ounces. The calculator is supported by one year limited warranty and comes along with a user guide manual.

Casio FX83ES Scientific Calculator
Casio FX83ES Scientific Calculator is newly introduced in the market. It features revolutionary Natural Textbook Display (NTD) and 249 functions and such key features will enable to enter expressions similar in your textbooks.

It has a twin line display on an LCD dot matrix. It consists of 7 memories and with 79 bytes formula memory. And the other features include logarithm, trigonometric functions, exponential regression, fractions, multi-replay, reset, and 24 parentheses.

The unit is protected by a slide-on hard plastic case and with a plastic keyboard. It measures 13.7 (H) x 80 (W) x 161 (D) mm and weighs 110 grams. It shuts off automatically and has a battery life of 17,000 hours.

This computing device is user-friendly. It can be used by grade school or high school students.

Texas TI-30X IIB Scientific Calculator
This is a cost effective and dependable scientific calculator for classroom use. It is helpful to students studying Science, Statistics, General Math, Geometry, Trigonometry, and Algebra 1 & 2.

The calculator has a 2-line display. The top line can exhibit entries up to 11 characters and can scroll up to 88, right and left. While the bottom or the result line can accommodate 2-digit exponent and up to a 10-digit answer. The previous entry in the calculator can be even reviewed to look for patterns.

TI-30X IIB has menus which allow students to choose appropriate settings for any Math and Science concepts. The fraction features of the calculator enable to perform mixed numbers and fractions operations. Its conversions are in decimals or fractions.

Other features are basic scientific and trigonometric functions, with πi as the symbol in radian mode, with editing expressions of statistical data elements and more.
