Welcome here to this Free Online Polynomial, and Scientific Calculator. You can perform operations with polynomials (+, -, *, /), find roots; operate logarithmic, trigonometric, matrix or exponential functions, or define custom functions, in the field of real or complex numbers. The calculator incorporates the constants 'pi' and 'e'.

Also you can enter binary, octal or hexadecimal numbers by prefixing &b, &o and &h and get the output in each of these bases, checking the respective box. Other options are the calculus of derivatives, integrals, Lagrangian interpolation, matrices operations and resolution of systems of equations. In many cases, you may glance at the examples or to the intermediate steps.
