Support in the processing of our modules

When editing our workshops there are a few typical sources of errors, which are listed here. If you receive an error message, this may be due to the notation required by the Julia programming language.

Typical input error Wrong input Correct input
Comma as decimal separator 1,5 1.5
Wrong arithmetic symbol for multiplication 2 x 4 2 * 4
Use of sine, cosine and tangent in radians instead of degrees sin(), cos(), tan() sind(), cosd(), tand()
Incorrect call of arcussine, arcuscosine and arcustangent (degree measure) sin^(-1), cos^(-1), tan^(-1) asind(), acosd(), atand()
Enter the number π as a character π pi
Copy formulas from text sin(440-2π-t) sin(440*2*pi*t)
Column vectors without a semicolon between entries [1 2 3 4] [1; 2; 3; 4]
Systems of equations or matrices without a semicolon at the end of each line

[ 1 2 3
  3 1 0
  3 1 -1 ]

[ 1 2 3;
  3 1 0;
  3 1 -1 ]
