FAQ
What is the difference between a scientific and a regular calculator?
A scientific calculator handles trig functions, logarithms, exponents, and more — while a basic one only does addition, subtraction, multiplication, and division.
Which trig functions are supported?
All the common ones: sin, cos, tan, and their inverses (asin, acos, atan).
Degrees vs radians — which should I use?
Depends on your problem. Most high school math uses degrees; calculus and higher math usually use radians. Pick the wrong one and your trig results will be way off.
Is this tool free?
Yes — completely free. No accounts, no paywalls. Just open the page and go.
Does my data get sent to a server?
No. Everything runs in your browser. Your data never leaves your device.
Does it work on my phone?
Absolutely. Works great on phones, tablets, and desktops alike.
