How to use the Scientific Calculator
- Choose a scientific function such as a root, power, logarithm, sine, cosine, or tangent.
- Enter X; open More options to enter Y for a power or yth root.
- Read the rounded result and the additional higher-precision value.
Powers, roots, logarithms and trigonometry
This scientific calculator evaluates one selected function at a time. Powers
use x^y; yth roots use x^(1/y); natural logarithms use base e; and
base-10 logarithms answer which power of ten produces the input.
Sine, cosine and tangent use angles in degrees. The calculator converts the entered angle to radians before applying the trigonometric function:
radians = degrees × π / 180The function terminology follows OpenStax Precalculus 2e.
With your numbers
- Evaluate √9 using the selected scientific function.
- Result = 3.

Common questions about the Scientific Calculator
- Are trigonometric angles in degrees or radians?
- Angles are entered in degrees. For example, sine of 30 degrees is 0.5.
- When is Y used?
- Y is used by the power and yth-root functions. Other functions only use X.
- What is the difference between ln and log?
- ln uses base e, while log₁₀ uses base 10.
- Why does the displayed result have fewer digits?
- The headline is rounded for readability. A higher-precision representation is shown below it.
