Scientific Calculator

sin, cos, tan, sec, csc, cot and their inverses, sinh, cosh, tanh and the other hyperbolic functions, sqrt, cbrt, nthRoot, exp, log, ln, log10, log2, abs, round, floor, ceil, factorial, gamma, combinations, permutations, gcd, lcm, mod, hypot, min, max and more. Constants are pi, e, tau, phi and i. Write powers with ^ and factorials as factorial(n).

In degree mode, sin, cos, tan, sec, csc and cot read plain numbers as degrees and asin, acos, atan and atan2 return degrees, so sin(30) = 0.5 and asin(1) = 90. In radian mode the same functions use radians, so sin(pi / 6) = 0.5. Hyperbolic functions always use plain numbers.

Both log(x) and ln(x) are the natural logarithm with base e. Use log10(x) for base 10, log2(x) for base 2 and log(x, b) for any base b, so log(8, 2) = 3. The Logarithm Calculator also detects exact results.

The tangent of 90 and 270 degrees is undefined, because the cosine is zero there. Instead of returning a huge number caused by rounding, the tool reports an undefined result. The same applies to cot at 0 and 180 degrees.

Floating point math gives a tiny leftover such as 1.2e-16 for sin(180 degrees) or sin(pi). The calculator treats trigonometric results smaller than 1e-15 as zero, which is what you expect from a calculator. Other results keep their full precision before rounding.

Yes, operations such as sqrt(-9) or ln(-1) return complex results like 3i, shown as a + bi. You can also enter complex values directly with i. Use the Complex Number Calculator for polar forms and arguments.

Factorials are computed in double precision, so the factorial of 170 is the largest finite value and anything above returns Infinity. combinations and permutations accept n up to 10,000. For exact large counts use the Permutation and Combination Calculator.

Standard precedence applies: parentheses first, then factorials, then powers from right to left, then multiplication and division, then addition and subtraction. So 2^3^2 is 2^9 = 512 and -2^2 is -4. Add parentheses whenever you want a different order.

No, this calculator works with plain numbers only and rejects unknown names such as x. Use the Expression Evaluator for units like cm or kg and conversions between them. For expressions with variables, use the Expression Simplifier or the Derivative Calculator.

Six by default, and you can choose from 0 to 15. Trailing zeros are removed and values too small for the chosen precision are written in scientific notation. Very large results also use scientific notation, such as 1.5e+25.
