A scientific calculator is a type of electronic calculator. But usually it is not always handheld; it designed to calculate problems in science (especially physics), engineering, and mathematics. Scientific calculator has almost completely replaced slide rules in almost all traditional applications, and it is widely used in both education and professional settings. The feature set differs between manufacturers and models; however, the defining features of a scientific calculator like Scientific notation for calculating large numbers, floating point arithmetic ,logarithmic functions, using both base 10 and base e ,trigonometry functions, exponents and roots beyond the square root, etc…
Scientific calculators are used widely in any situation where quick access to certain mathematical functions is needed, especially those such as trigonometric functions that were once traditionally looked up in tables. The benefit of a scientific calculator is to Save time and reduce errors with the unparalleled computing power. It have a clean interface that’s easy to read and easy to use. A scientific calculator is used routinely by scientists and engineers. A good scientific calculator must be very precise and it must handle the huge dynamic range of numbers that are encountered in our understanding of science. Scientific calculators must provide functions that help us analyze data as well as functions that simply calculate numbers.
