Scientific calculators allow you to solve limits directly without using long, written calculations on pen and paper. In high school level education, calculus includes the study of concepts such as functions and limits. Scientific calculators also include shorthand buttons for constants such as “pi” so you can easily incorporate them into calculations and formulae. Scientific calculators allow you to calculate and represent trigonometric ratios and formulae. Trigonometry involves measuring and calculating the sides and angles of triangles in relation to each other and is generally taught as a subset of geometry in the education system. It represents calculations and figures as an approximal formula rather than a standard integer. This type of numerical representation is used when dealing with very small or very large numbers. An example of scientific notation would be ”m × 10n.”

When numbers are too large and long to be written in decimal form, scientific notation is used instead. Different makes and models may also include extra features. Today’s scientific calculators can perform a core set of calculations and functions. Casio is particularly associated with their popular FX series, such as the Casio FX-991EX, commonly used by students in school. Since then, other brands have taken over and dominated the scientific calculator market, including Sharp, Casio and Canon. It used transistor logic, CORDIC algorithm for trigonometry and was based on RPN entry. Of all the different versions of the modern calculator, the 1968 Hewlett-Packard HP-9100A can be defined as the first scientific calculator. They’re still one of the most popular brands of scientific calculators as we know them today. Hewlett-Packard quickly followed in 1975 with the first handheld programmable calculator at $795.īy 1985, Casio had released their first graphing calculator and quickly continued iterating on this model. The first pocket calculator with an LED display was released by BUSICOM in 1971 and cost $395. Throughout the 1970s, calculators continued to evolve.
