Scientific Calculator

A scientific calculator performs mathematical functions beyond basic arithmetic, including trigonometry (sin, cos, tan), logarithms (log, ln), exponents, roots, factorials, and more. It's essential for students, engineers, scientists, and anyone working with advanced math.

Log (log₁₀) is the logarithm base 10, commonly used in science and engineering. Ln is the natural logarithm (logₑ) base e (≈2.718), used in calculus and natural growth/decay problems. log₁₀(100) = 2, while ln(e) = 1.

These trigonometric functions relate angles to ratios of sides in right triangles. Sin = opposite/hypotenuse, Cos = adjacent/hypotenuse, Tan = opposite/adjacent. They're essential for physics, engineering, navigation, and computer graphics.

Degrees divide a circle into 360 parts, while radians use the relationship between arc length and radius (2π radians = 360°). One radian ≈ 57.3°. Radians are preferred in calculus and physics; degrees are common in everyday use.

Factorial is the product of all positive integers up to n. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120. Used in permutations, combinations, probability, and series expansions. By definition, 0! = 1.

e ≈ 2.71828 is the base of natural logarithms. It appears naturally in compound interest, population growth, radioactive decay, and calculus. The function eˣ is unique in being its own derivative.
