How the Scientific Calculator works
The GKCalculators Scientific Calculator is a full-featured math tool with a complete keypad covering trigonometric functions, exponents, roots, logarithms, parentheses grouping, and memory storage — built for students, engineers, teachers, and anyone who needs more than basic arithmetic.
A full scientific keypad with trig (degrees/radians), logs, powers, roots, constants and factorials. Results are added to a running history.
Formula
General expression structure: result = f(g(x)) following PEMDAS; Trig: sin(θ), cos(θ), tan(θ); Inverse trig: arcsin(x), arccos(x), arctan(x); Logarithms: log(x) = log₁₀(x), ln(x) = logₑ(x); Powers & roots: x^y, √x, ⁿ√x; Quadratic example: x = (−b ± √(b²−4ac)) / (2a)
Pro tips
- Wrap expressions in parentheses to control the order of operations.
Key terms
- Operator Precedence
- — The rule set (PEMDAS/BODMAS) that determines the order in which operations are evaluated in a mathematical expression.
- Radian
- — An angle unit where a full circle equals 2π radians (~6.2832), used as the default in most calculus and physics contexts.
- Common Logarithm (log)
- — A logarithm with base 10, where log(x) answers the question 'to what power must 10 be raised to get x?'
- Natural Logarithm (ln)
- — A logarithm with base e (~2.71828), fundamental to continuous growth, decay, and calculus.
- Inverse Trigonometric Function
- — Functions such as arcsin, arccos, and arctan that return an angle when given a trigonometric ratio.
- Memory Register
- — A temporary storage location on the calculator that holds a numeric value for recall during multi-step calculations.
