etc., up to the seconds. Finally, report on the console the outcome based
on these boolean values.
Exercise 1.4 (From a linear to a quadratic solver)
We consider a linear equation y = ax + b where a and b are given
parameters (using double type). Write a program that calculates the
root of ax + b = 0. That is, the y -intercept of the line with the x -axis. How
to extend it to quadratic equations ax 2 + bx + c = 0? Observe numerical
rounding phenomena that emphasize that roots slightly differ from their
mathematical roots because of finite precision of number representations.

Exercise 1.5 (Java syntax for constant declarations)

Explain why the program below does not compile. How should it be
modified in order to compile properly?

class ConstantExercise
static final int MAX = 10;

public static void main( String [ ] args )

double fi ;
static final double GoldenRatio=(1.0d+Math. sqrt (5) ) /2.0;

for ( int i=0;i < MAX; i ++)
{ f i=GoldenRatio ∗ Math . cos ( 2 . 0 ∗ Math . PI ∗ i/( double )MAX) ;
System . out . println ( "i=" +i+ " f(i)=" +fi ) ;

}
}
