Perform arithmetic, powers, roots, trigonometric functions, logarithms, and other operations shown on the scientific keypad.
Scientific Functions and Angle Units
Use the available keys for arithmetic, powers, square roots, trigonometric functions, logarithms, and the displayed constants. The sine, cosine, and tangent functions interpret angles in radians; convert degrees to radians before entering an angle measured in degrees.
Precision and domain
Displayed results are rounded for readability and may differ slightly from high-precision software. Some operations have restricted domains—for example, real square roots of negative numbers and logarithms of non-positive values are not defined in the real-number system.
Example and limitations
Trigonometric functions use radians. Convert degree measurements to radians before entering them, and check the displayed function labels before evaluating a scientific expression.
