Scientific Calculator Guide: Functions & Usage Tips

What is a Scientific Calculator?

A scientific calculator goes beyond basic arithmetic to handle trigonometry (sin, cos, tan), logarithms (log, ln), exponents, roots, and other advanced mathematical functions essential for science, engineering, and higher mathematics.

Key Functions Explained

Trigonometric Functions

• sin(x): Sine of angle x (in radians or degrees)
• cos(x): Cosine of angle x
• tan(x): Tangent of angle x

Logarithmic Functions

• log(x): Base-10 logarithm (log₁₀)
• ln(x): Natural logarithm (base e ≈ 2.718)

Power Functions

• x²: Square of x
• xʸ: x raised to power y
• √x: Square root of x
