A scientific calculator is an advanced calculator that goes beyond basic arithmetic. It includes functions for trigonometry, logarithms, exponents, factorials, and more. Scientific calculators are essential tools for students studying algebra, trigonometry, calculus, physics, chemistry, and engineering.
Angles can be measured in degrees or radians. Degrees are more intuitive for everyday use — a full circle is 360°. Radians are used in higher mathematics and physics — a full circle is 2π radians. To convert degrees to radians, multiply by π/180. To convert radians to degrees, multiply by 180/π.
A logarithm answers the question: to what power must a base be raised to produce a number? For example, log(100) = 2 because 10² = 100. The natural log (ln) uses base e (2.71828...).
A factorial (n!) is the product of all positive integers up to n. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120. Factorials are used in probability, statistics, and combinatorics.
Euler's number (e ≈ 2.71828) is a mathematical constant that is the base of natural logarithms. It appears naturally in growth and decay problems, compound interest, and many areas of mathematics and physics.
