Frequently Asked Questions
Is the Scientific Calculator free?
Yes, ApexSofteck Tools's Scientific Calculator is completely free. Use it unlimited times without any registration required.
Can I use keyboard shortcuts?
Yes! Use number keys, operators (+, -, *, /), Enter to calculate, Backspace to delete, and Escape to clear all.
What's the difference between DEG and RAD?
DEG uses degrees (0-360°) for trigonometric calculations. RAD uses radians (0-2π). Most school math uses degrees; advanced math uses radians.
How do I calculate square roots and powers?
Use the √ button for square roots and x^y button for exponents. Enter the base, press x^y, then enter the exponent.
What functions are supported?
sin, cos, tan, log (base 10), ln (natural log), √ (square root), ^ (power), and all basic arithmetic operations.
