Scientific Calculator: sin cos

A scientific calculator that behaves like the one on your desk. Type the whole expression, see the result update as you go, and keep the working out on screen instead of in your head.

Everything runs on your phone, with no account and no connection.

WHAT IT CALCULATES

• Trigonometry — sin, cos, tan and their inverses, in degrees or radians
• Logarithms — ln and log, plus eˣ and 10ˣ on the SHIFT layer
• Powers and roots — x², x³, xʸ, square root and cube root
• Reciprocal (1/x), factorial (n!) and percent
• The constants π and e
• Parentheses, with the closing ones filled in for you

HOW IT WORKS

Write the expression the way you would on paper. 2π, 3(4+5) and 2sin(30) all multiply on their own, so you can skip the × key. The line under your input shows the running answer before you even press equals.

Results carry ten significant digits and switch to scientific notation for very large and very small numbers. The decimal separator follows your language: a comma where your school taught you a comma.

MEMORY AND HISTORY

MC, MR, M+ and M− hold a running total while you work through a longer problem. Ans drops the previous result into the next expression.

The history sheet keeps your recent calculations. Tap any line to load that expression back into the keypad and edit it.

BUILT FOR

• Secondary school and university coursework
• Homework, revision and lab work
• Engineering, surveying and trade calculations
• Anyone who wants a calculator that opens instantly

OFFLINE, ALWAYS

Every calculation happens on the device. No sign-up, no connection, no personal data collected. It works on the train, in a basement lab and on a plane.

PRO

The full keypad, degrees and radians, memory keys and history are all available without paying. Pro raises the number of calculations kept in history from 20 to 500, adds the matte black and arctic white shells, and removes the ads.

Pro starts with a 7-day free trial. Ads are still shown during the trial. After that it renews as a weekly subscription and the ads stop. Cancel anytime in Google Play.
