Online scientific calculator - full range of mathematical functions

Online scientific calculator replaces physical calculators (Casio fx, Texas Instruments) in the browser. Supports all basic and advanced math functions: trigonometric, logarithmic, exponential, factorial, combinatorics and math constants.

Trigonometric functions

sin(x), cos(x), tan(x): sine, cosine, tangent. asin(x), acos(x), atan(x): arcs (inverse). DEG/RAD mode: sin(30°) in DEG = 0.5, sin(π/6) in RAD = 0.5. sinh(x), cosh(x), tanh(x): hyperbolic functions. atan2(y,x): quadrant-aware arctan (for vectors).

Logarithms and powers

log(x) or log10(x): logarithm to base 10. ln(x): natural logarithm (base e). log2(x): binary logarithm. exp(x) or e^x: exponent of (e^x). x^y or pow(x,y): exponentiation. sqrt(x): square root. cbrt(x): cube root. x!: factorial. nCr(n,r): combinations (n by r). nPr(n,r): permutations.

Mathematical constants

π (pi) ≈ 3.14159265358979. e (Euler) ≈ 2.71828182845905. φ (golden proportion) ≈ 1.61803398874989. √2 ≈ 1.41421356237. √3 ≈ 1.73205080757. Physical constants: c (speed of light) = 299,792,458 m/s. g ≈ 9.80665 m/s². h (Planck) ≈ 6.626×10⁻³⁴ J s.

History and Memory

Calculation History: List of previous expressions and results. Click to repeat or edit. Memory: M+, M-, MR, MC (add, subtract, recall, clear). Variables: assign the result to a variable (x=5, then x*3). Multi-line expressions: solve multi-step equations.

FAQ

What is the order of operations in a scientific calculator?

PEMDAS (English) / BODMAS (English): Brackets → Powers/Roots → Multiplication/Division → Addition/Subtraction (from left). 2+3×4=14 (not 20). 2^3^2 = 2^(3^2) = 2^9 = 512 (right-sided exponentiation). The calculator respects the standard order of operations.

What is a factorial and where is it used?

n! = n × (n-1) × ... × 1. 0! = 1 (by definition). 5! = 120.10! = 3,628,800.20! = 2.43 × 10^18. Applications: combinatorics (permutations, combinations), probability, Taylor series (sin x = x - x³/3! + x⁵/5! - ...).

How to calculate combinations and permutations?

Combinations C(n,k) = n! / (k! × (n-k)!): how many k-element subsets of n elements. C(52.5) = 2,598,960 (possible poker hands). Permutations P(n,k) = n! / (n-k)!: how many k-element strings with n elements (order important). P(10,3) = 720.

How to check trigonometric calculations?

Make sure DEG/RAD is set properly. sin(90°) = 1 (DEG), sin(π/2) = 1 (RAD). Check the identity: sin²(x) + cos²(x) = 1 always. cos(0) = 1, sin(0) = 0. tan(45°) = 1. tan(90°) = infinity (calculator error).

Which scientific calculators are the most popular?

Casio fx-82: the most popular school calculator in Poland. Casio fx-991EX (ClassWiz): advanced, supports equations and matrices. Texas Instruments TI-84: US standard for schools. Wolfram Alpha: online, solves symbolic equations. Python (math.sin, math.log): for programmers.
