DEG

Keyboard: digits + + − × ÷ ^ ( ), Enter = compute, Backspace = delete, Esc = AC. Calculator state lives only in this tab — no server storage.

Tips

Toggle DEG/RAD with the MODE key — affects sin / cos / tan and their inverses.
Use SHIFT to access the alternate label on a key (e.g. SHIFT + sin → sin⁻¹).
Ans recalls the last answer; great for chained computations.
Memory: M+, M−, MR recall, MC clear.
Live result: as you type, the bottom line shows the running evaluation. Press = to commit it as Ans.
