Scientific Calculator: Trig

Scientific Calculator puts the functions you need for school, university and engineering work on one screen: trigonometry in radians or degrees, logarithms, powers and roots, factorials, scientific notation, memory and brackets. The whole expression is shown above the result, so you can follow what was typed.

What you get
• Trig and inverse trig: sin, cos, tan and their inverses, plus hyperbolic functions
• Rad and Deg switch for angle units
• Algebra keys: x², x³, xʸ, square and cube roots, the y-th root, 10ˣ, ln, log base 2, log base 10 and log base y, factorial
• Constants π and e, and a random number key
• Scientific notation with EE, and memory keys M+, M- and MRC
• Brackets, sign change and percent

Where it helps
• Homework and practice in algebra, trigonometry and precalculus
• Checking a science or engineering calculation
• Quick logarithms and exponents without a separate app
• Working through nested brackets while keeping the whole expression visible

Made for daily use
• Light and dark theme
• 28 languages, with right-to-left layout where it belongs

A new app
Built on the Calculator.io calculator engine. A More calculators link opens the full Calculator.io app, with 170+ tools for math, money, health and dates.

The app is supported by banner ads. Results are rounded to a limited number of significant digits, so check critical values another way. Calculators may not be allowed in every exam.
