Scientific Calculator

A scientific calculator goes beyond basic arithmetic to handle the mathematical operations needed in science, engineering, and advanced academics — trigonometric functions, logarithms, powers, roots, factorials, and physical constants. Basic operations: Enter numbers and operators as you would write them. The display shows your expression as you type so you can verify it before calculating. Use parentheses to control order of operations. Trigonometric functions: sin, cos, tan — standard trigonometric ratios. asin, acos, atan — inverse trigonometric functions (returns angle from ratio). sinh, cosh, tanh — hyperbolic functions used in calculus and physics. Degree/Radian mode: Toggle between DEG and RAD before entering trig functions. Sin(90) in degrees equals 1. Sin(90) in radians equals 0.894. Always confirm your mode first. Logarithms and exponentials: log — base-10 logarithm. ln — natural logarithm (base e). e^x — e raised to power x. 10^x — 10 raised to power x. Powers and roots: x^y — x raised to power y. x^2 — square. sqrt — square root. cbrt — cube root. n! — factorial. Useful for permutations and combinations in statistics. Constants: pi (3.14159...) — ratio of circle circumference to diameter. e (2.71828...) — base of natural logarithm, fundamental in calculus. Memory: M+ adds to memory, MR recalls, MC clears. Useful for intermediate results in multi-step calculations.
