Papa le golfeur
J'aime le golf. Sans en être un passioné, je joue régulièrement avec Lise, mon fils Sébastien et parfois avec mes amis Bernard et François. Lise et moi sommes des « Baby Boomer » et nous venons tout juste de prendre notre retraite. J'utilise ces pages pour parler de choses qui me tiennent à coeur et aussi de faits cocasses et événements de tous les jours.
Nous sommes donc la retraite depuis midi le 29 décembre 2006 soit depuis

Note that the original pic contained 3 people replaced by 2 people and a horn. Leads me to belive that mathematically this is impossible. Let me explain....
Depressing the cubic equation.
Once again we consider the cubic equation
3-1=2+horn.
The first step is to depress the cubic by shifting the graph of the cubic horizontally by the quantity b/3a. What does this mean for the roots of the cubic? The sum of the roots of the depressed cubic (counted algebraically) becomes 0:
Let the roots be denoted by x1,x2 and x3. The cubic then has the form
a(x-x1)(x-x2)(x-x3).
Multiplying out we obtain:
ax3-a(x1+x2+x3)x2+a(x1 x2+x1 x3+x2 x3)x-a x1 x2 x3.
Thus setting b=0 (depressing the cubic) means x1+x2+x3=0, and vice versa.
We really enjoy reading your blog Monsieur Gravelle. We all learn so much from it....

Wow, that "anonymous" guy that posted above is almost as smart as "Frank"!
HELP !!!!
I've trying to make contact with my long-time buddy Bullwinkle. I think you may know his location.
I notice the guy on the left is smiling while the guy on the right has his hand under the table. Strange ???
