Scientific Calculator Online A scientific calculator online handles trigonometry, logarithms, exponents, roots, factorials, and combinatorics in the browser without installing software. The mathematical functions used are defined in IEEE 754 for floating-point arithmetic and the ECMAScript Math object for browser implementations — useful for engineering calculations, statistics, physics homework, and any math beyond the four basic operations that a standard calculator can't handle. --- What makes a calculator scientific? A basic calculator performs +, -, ×, ÷ with decimal support. A scientific calculator adds: | Function Category | Functions | |------------------|-----------| | Trigonometry | sin, cos, tan, arcsin, arccos, arctan | | Hyperbolic | sinh, cosh, tanh | | Logarithms | log₁₀,…
Frequently Asked Questions
What functions does a scientific calculator have?
A scientific calculator includes trigonometric functions (sin, cos, tan and their inverses), logarithms (log base 10 and natural log), exponents and roots, factorial, combinatorics (nCr, nPr), hyperbolic functions, and constants like π and e.
How do I calculate sin, cos, tan online?
Enter the angle and click sin, cos, or tan. Make sure the angle mode (degrees vs radians) matches your input — sin(90°) = 1 in degrees, but sin(90) ≈ 0.894 in radians because 90 radians is not a right angle. Most scientific calculators default to degrees.
What is the order of operations?
PEMDAS / BODMAS: Parentheses first, then Exponents, then Multiplication and Division (left to right), then Addition and Subtraction (left to right). A scientific calculator follows this order automatically, but verify by using parentheses when uncertain.
What is EXP on a calculator?
EXP (or E or ×10^) is scientific notation entry. '5 EXP 3' means 5 × 10³ = 5000. It's used for very large or very small numbers: Avogadro's number is 6.022 EXP 23 (6.022 × 10²³). Not to be confused with the exp() function, which computes e^x.
How do I calculate logarithms?
log(x) computes the base-10 logarithm; ln(x) computes the natural logarithm (base e ≈ 2.718). To find log base b of x: log_b(x) = log(x) / log(b). Example: log₂(8) = log(8)/log(2) = 3.
