- Read as: x^2 - 2 with angles in radians.
- Solve f(x) = 0 on the bracket [0, 2].
- f(0) - 0 = -2 and f(2) - 0 = 2: the signs differ, so a solution lies between them.
- Bisecting the bracket to a width below 1e-13 gives x = 1.41421356237.
- Check: f(1.41421356237) - 0 = -1.28563826252e-13.

What the Equation Solver — Find x calculates
Evaluates a scientific expression with trigonometric, inverse and hyperbolic functions, logarithms to any base, roots, powers, factorials and combinatorics, honouring standard operator precedence and an explicit angle unit; also tabulates y = f(x) for graphing, solves f(x) = target for x by bisection, and simplifies and differentiates an expression symbolically.
How to use this Equation Solver — Find x
Enter Expression, Angle unit, Significant figures and Solve for f(x) =. Result updates as you type. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Result, Full-precision result and Result with separators.
The method follows NIST Digital Library of Mathematical Functions, Chapter 4 (Elementary Functions), Abramowitz & Stegun, Handbook of Mathematical Functions, Chapter 4, ECMA-262, ECMAScript Language Specification, §21.3 The Math Object, Burden & Faires, Numerical Analysis, §2.1 The Bisection Method and Stewart, Calculus: Early Transcendentals, Chapter 3 (Differentiation Rules).
What you can compare
Change one input at a time to see how it affects Result, Full-precision result and Result with separators. The inputs you can vary are Expression, Angle unit, Significant figures, Solve for f(x) =, Window / bracket: smallest x and Window / bracket: largest x.
Results are general information, not financial, tax, legal, medical or engineering advice. Check any decision that matters with a qualified professional.
