A scientific calculator performs complex mathematical operations including trigonometry, logarithms, exponents, roots, and factorials. It is essential for students, engineers, and scientists.
Radians and degrees are units for measuring angles. A full circle is 360° or 2π radians. To convert: radians = degrees × (π/180). Scientific work typically uses radians.
The natural logarithm (ln) uses base e (≈2.71828). It is the inverse of e^x and is widely used in calculus, physics, and engineering for modeling growth and decay.
A factorial (n!) is the product of all positive integers up to n. For example, 5! = 5×4×3×2×1 = 120. Used in permutations, combinations, and probability.
