are the parameters used to chose one specific element of the family of functions.


For example, let's say we want to implement a function that given the spring constant  
For example, let's say we need to compute the time evolution of the elongation of
a spring for different values of the spring constant  


<math> k </math>
<math> k </math>
 
and the initial elongation
 
<math> x_0 </math>
 
of a spring, computes the time evolution of the elongation
 
<math> x (t ; x_0, k) </math>
 
by solving the Cauchy problem
 
<math> x' = - k x\\ x(0) = x_0 </math>
