Type an expression using functions like sin, cos, log, ln and √ together with the constants π and e. The answer updates live as you type, so you can build up a long calculation and watch it resolve.
Trigonometry in degrees or radians
The calculator includes sin, cos and tan plus their inverses (asin, acos, atan). Switch between degrees and radians with the DEG/RAD toggle — the mode is shown on screen so you always know how angles are being read. Press SHIFT to reach the inverse functions printed above each key.
Logarithms, powers and roots
Work with natural logs (ln), base-10 logs (log), the exponential functions (eˣ and 10ˣ), square and cube roots (√ and ∛), and arbitrary powers with the caret, such as 2^10. Dedicated x² and x³ keys make common powers a single tap.
Constants and the last answer
Insert π and e directly as constants, and reuse your previous result with the Ans key to chain one calculation into the next without retyping it. Parentheses let you nest functions cleanly, for example sin(30) + √(16).
Clear, accurate results
Answers are shown to full precision and switch to scientific notation for very large or very small numbers, so you never lose significant digits. Tap any value on screen to edit it, paste a full expression from elsewhere, and copy the result with one tap. Everything runs privately in your browser with no sign-up.
