3.1 The Fundamentals


3.1.1 Basic Operations



• Scilab example,


3.1.2 Exponents


• The basic properties of exponents are so important they demand some sort of mention


• Scilab example,


3.1.3 Basic Polynomials



• The quadratic equation.


• e.g.,

• Complex roots will occur when,

• Cubic equations can be solved explicitly, although this is too much for common memorization.



• On a few occasions a quartic (4th order) equation will also have to be solved. This can be done by first reducing the equation to a quadratic,



• In Scilab,
