Compute advanced math formulas, trigonometry, logarithms, exponentials, and algebra instantly. Free online scientific calculator.
Supports Javascript syntax like: sin(x), cos(x), tan(x), sqrt(x), log(x), abs(x), PI, E
Solve equations instantly using our Scientific Calculator. Specially optimized for teachers, engineers, students, and programmers checking equations locally in the browser. You can also calculate percentages using the Percentage Calculator or list metrics with our Average Calculator.
This tool operates entirely in your browser using pure JavaScript, ensuring maximum privacy and instant calculations without any server delays. No data is stored, and no signup is required. You can return to our Home Page for more tools.
Type your formula or mathematical expression into the expression container and press Enter or click 'Evaluate Expression'. The result appears in the adjacent panel. Check standard mathematical functions syntax on MDN Web Docs.
This tool supports standard algebraic equations, trig functions (sin, cos, tan, asin, acos, atan), math powers, sqrt (square root), logs (natural logarithm), and constants like PI and E.
By default, standard trigonometric functions (like sin, cos, tan) in Javascript calculate values in Radians. To use degrees, multiply your angle by (Math.PI / 180).
