Scientific Calculator

A full-featured scientific calculator with trigonometry, logs, powers and memory.

Full-featured scientific tool with trigonometry, logarithms, powers, memory and more.

Memory:

Tip: press 2nd to access inverse trig and 10ˣ. Functions act on the currently displayed value.

How to use the scientific calculator

Trigonometry — sin, cos and tan use the selected angle mode (degrees or radians). Toggle with 2nd for inverse functions.
Logs & exponents — log is base 10, ln is natural, xʸ raises to any power, 10ˣ and eˣ are convenient shortcuts.
Memory — M+/M− add/subtract the display, MR recalls, MC clears.
Parentheses — build more complex expressions like sin(45) or 2 ( 3 + 4 ).

Example: sin(30°) = 0.5. Set the angle to DEG, press sin, then type 30 — or type 3 0 then press sin.
