Frequently Asked Questions
What trigonometric functions does this calculator support?
It supports sin, cos, tan and their inverse functions arcsin, arccos, and arctan. You can toggle between degree and radian mode to match the unit your problem requires.
Can I use this calculator on my phone?
Yes, the calculator runs entirely in the browser and works on phones, tablets, and desktops. The responsive layout adapts to smaller screens so buttons remain easy to tap.
Does it handle parentheses and order of operations?
Yes, you can nest parentheses to any depth and the calculator follows standard mathematical order of operations. Exponents are evaluated before multiplication, which is evaluated before addition.
What constants are built in?
The calculator includes pi, Euler's number e, the golden ratio, and the speed of light among other commonly used constants. Tap the constants button to insert them directly into expressions.
Is the calculation history saved between sessions?
No, the history is stored only during the current browser session. Once you close the tab or refresh the page, the history is cleared. Copy any results you need to keep before leaving.
