Frequently Asked Questions
Tap the function (e.g. sin), enter the angle, close the bracket and press =. Angles are in degrees, so sin(30) = 0.5.
Use x^y for powers (e.g. 2 ^ 10 = 1024) and the √ key for square roots (√(81) = 9).
Trigonometric functions use degrees, which is what most everyday and school problems expect.
