Scientific calculators are essential tools in mathematics, science, and engineering. They extend the capabilities of basic calculators by including functions for trigonometry, logarithms, exponentials, and statistical analysis. The first electronic scientific calculator, the Hewlett-Packard HP-9100A, was introduced in 1968. Modern scientific calculators, including digital versions, continue to play a crucial role in education and professional fields, offering quick and accurate computations for complex mathematical operations.
This scientific calculator uses the math.js library to perform various mathematical operations. When a calculation is entered, the math.evaluate() function processes the input string as a mathematical expression. For example, to calculate sin(30°):
1. The user enters "sin(30)" into the display.
2. Upon pressing "=", math.evaluate("sin(30)") is called.
3. The math.js library converts the input to radians and calculates the sine.
4. The result is displayed, rounded to a maximum of 13 digits.
For larger results, the calculator uses scientific notation. Other operations like logarithms (log()), square roots (sqrt()), and exponents (^) are processed similarly, utilizing the corresponding math.js functions.
