About the Scientific Calculator

This free online scientific calculator handles advanced mathematical operations beyond basic arithmetic. It supports trigonometric functions (sin, cos, tan and their inverses), logarithms (log base-10 and natural log ln), square roots, cube roots, powers (xy), factorials (n!), absolute values, and the mathematical constants π and e.

You can switch between radian and degree modes for trigonometric calculations. The calculator is ideal for students, engineers, and anyone working with advanced mathematics.

Frequently Asked Questions

What functions does this scientific calculator support?

It supports: sin, cos, tan, sin&sup-1;, cos&sup-1;, tan&sup-1;, log, ln, √x, ³√x, x², x³, xy, n!, |x|, 1/x, π, e, and EXP notation.

What is the difference between RAD and DEG mode?

RAD (radian) and DEG (degree) modes affect how trigonometric functions interpret angle inputs. For example, sin(90) in DEG mode = 1, while sin(90) in RAD mode = ~0.894. Most engineering and physics problems use radians; geometry and everyday use typically uses degrees.

Can I use a keyboard with the scientific calculator?

Yes. You can type numbers and operators directly from your keyboard. Press Enter or = to compute, and Backspace to delete.
