There are two main types of calculators suitable for engineering: scientific calculators and graphing calculators. Scientific calculators often have a two line display, and while they offer a wide range of functions, they are not as versatile as graphing calculators. Scientific calculators are usually capable of calculating functions for trigonometry and algebra as well as a variety of basic math functions. Compared to graphing calculators they are more economically priced and are often easier to use than the more complicated graphing kind .
Graphing calculators have become essential in the math and engineering worlds. They are now required in most high schools and some middle schools. They are more expensive and difficult to use than scientific calculators, but they are capable of far more complex calculations in a wider range of fields. Graphing calculators offer a large square display capable of showing graphs of functions. They can be connected to a large number of peripheral units that can be used in fields like chemistry and biology, and they can connect to a computer for easy graph transferral.
