Detailed manual explaining every function, input parameter, and operational example for the Scientific Calculator.

Arithmetic (+, -, ×, ÷)

Function

Performs basic arithmetic operations.

Example Operation 4 + 4 = 8 | 20 ÷ 4 = 5

Percentage (%)

Function

Calculates standalone or relative percentage.

Example Operation 50% = 0.5 | 100 + 10% = 110

Trigonometry (sin, cos, tan)

Function

Computes trigonometric functions in DEG/RAD/GRAD modes.

Example Operation sin(30°) = 0.5

Inverse Trig (sin⁻¹, cos⁻¹, tan⁻¹)

Function

Computes arc-trigonometric functions.

Example Operation asin(0.5) = 30°

Logarithms (log, ln)

Function

Base-10 logarithm and natural logarithm.

Example Operation log(100) = 2 | ln(e) = 1

Exponents & Powers (xʸ, 10ˣ, eˣ)

Function

Calculates powers and exponential values.

Example Operation 2^3 = 8 | 10^2 = 100

Factorial (x!)

Function

Computes factorial of non-negative integers.

Example Operation 5! = 120

Combinatorics (nCr, nPr)

Function

Calculates combinations and permutations.

Example Operation nCr(5, 2) = 10 | nPr(5, 2) = 20

Physical Constants
