Scientific Mathematical Functions.

Mathematical functions and operators can be input directly, or via command menu item Math functions >
Basic functions, or command menu item Math functions > Advanced.
Calculations involving division and/or multiplication take precedence over those containing addition and
subtraction (BODMAS precedence). The inclusion of parenthesis allows calculations to be ordered. The
minus sign must be used to denote a negative number, e.g. 3 x -2.
A list of functions, their operators and examples now follow:

Basic Calculations.


Addition (plus): +

Subtraction (minus): -

Multiplication (times): *

Division (divided by): /

Percent (x per cent of y): %

Parenthesis:

Square root: sqrt

8.10 Powers, Logarithms, Etc.


Powers (to the power of x): pow

Exponent (10 to the power x): exp

Common logarithms (to base 10): log

Natural logarithms: ln

Euler: epow

Pi: pi

Modulo: mod
o
The mod function displays the modulus or remainder of x/y.
o
Example: 5 divided by 4 gives a remainder of 1 (i.e. 5mod4=1).

8.11 Trigonometry Functions.

Sine (in degrees): sin

Sine in radians: sinr

Cosine (degrees): cos cos 90

Cosine in radians: cosr cosr(4+7)

Hyberbolic cosine: cosh cosh0,75

Arcus cosine degrees (Inverse); acos

Tangent (degrees): tan tan 45

Tangent in radians: tanr tanr(4+7)

Hyperbolic tangent: tanh

Arcus tangent degrees (Inverse): atan

8.12 User Constants.

The variables x, y, and z can have any constant values assigned to them.
For example, they can be used to denote specific factors frequently used in your calculations. The
variable will then be used instead of a number, e.g. sqrtx will calculate the square root of this assigned
value x. To enter x, y or z you can either type this character directly into the calculation, or select the
corresponding item from the command menu.
