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,
