Scientific Functions
The Scientific section of the calculator includes several specialized operators and functions.
Operators
For some scientific calculations, you only need to enter a number followed by an operator to
obtain a result. These include:
,
,
,
,
,
,
, and
.
When you enter a number followed by one of these keys, the result is displayed immediately.
Example: To square 7, tap ‘7
’. The result is 49.
You can use the
key to raise a number y to the power of a number x.
Example: Tap raise 2 to the power of 3, tap ‘2
3 =’. The result is 8.
You can use the
key to enter a value in exponential notation.
Example: To enter 1.23 x 10
-8
enter ‘1.23
8 +/-’. The display shows 1.23e-8. You may now
perform calculations on this value.
You can use the
key to generate a random number between 0 and 1.
Using Trigonometry Functions
Trigonometric calculations such as sine, cosine, and tangent must be made in degree, radian, or
gradian mode. The calculator is set to degree mode by default, and returns to degree each time
the Pulse smartpen is turned off.
The
key toggles between degree, radian and gradian mode. If you use a trigonometry
function, or use the
key to change modes, an indicator of the current mode will appear.
