Numeric scientific calculator: trig, logs, powers, roots, factorial. It evaluates expressions; it does not show algebraic steps and is not a graphing CAS.

Formula

Uses JavaScript Math for sin, cos, tan, log, ln, powers, and roots. Trig is in radians unless the page is set to degrees.

How to calculate

  1. Set degrees or radians before trig.
  2. Enter the expression or tap the keys.
  3. Factorial n! is defined for non-negative integers on this page.

Example

sin(30°) = 0.5 when the calculator is in degree mode. In radians, sin(30) is sin(30 rad), not 0.5.

Common mistake

Degree/radian mode is the usual source of “wrong” trig. This is not Photomath: it will not rearrange a symbolic equation.

FAQ

Is this an engineering or scientific calculator?

It covers standard scientific functions (trig, logs, powers). It is not a CAS and does not show algebraic steps.

Does it graph functions?

No. Graphing and symbolic algebra are out of scope on this site.
