Frequently Asked Questions

How do I switch between degrees and radians?

Click the DEG/RAD button to toggle modes. Use degrees for practical problems (angles in everyday life) and radians for calculus and pure math. The current mode is shown on the display.

What trigonometric functions are available?

This calculator includes sin, cos, tan and their inverses (arcsin, arccos, arctan). Also available: hyperbolic functions (sinh, cosh, tanh) and their inverses. All work in both degree and radian modes.

How do I calculate logarithms?

Use LOG for base-10 logarithms and LN for natural logarithms (base e). For other bases, use the formula: log_b(x) = log(x) / log(b). The calculator also has 10^x and e^x for inverse operations.

Can I export my Scientific Calculator calculations?
