7.9 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.
7.10 Basic Calculations.
1. Addition (plus): 2+3
2. Subtraction (minus): 3-2
3. Multiplication (times): 3*2
4. Division (divided by): 7/8
5. Percent (x per cent of y): 7%50
6. Parenthesis: 3*(7+5)
7. Square root: sqrt 36
7.11 Powers, Logarithms, Etc.
1. Powers (to the power of x): 2pow3
2. Exponent (10 to the power x): 2exp-5
3. Common logarithms (to base 10): 5*log 70
4. Natural logarithms: 2/ln10
5. Euler: epow-3
6. Pi: pi*36
7. Modulo: 5mod4
a. The mod function displays the modulus or remainder of x/y.
b. Example: 5 divided by 4 gives a remainder of 1 (i.e.
5mod4=1).
7.12 Trigonometric Functions.
1. Sine (in degrees): sin90
2. Sine in radians: sinr(4+7)
3. Hyperbolic sine: sinh0,75
4. Arcus sine degrees (Inverse): asin0,5
5. Cosine (degrees): cos 90
6. Cosine in radians: cosr(4+7)
