La longueur de la corde 2008-12-24
Lucile pose la question :
Voici l'énoncé :

On appelle (C) un cercle de centre O et de rayon 6cm. A et B sont deux points du cercle (C) tels que AOB = 50°

Calculer la longueur de la corde [AB] (arrondi au millimètre). On justifiera soigneusement toutes les étapes.

Cela fait déja 1 semaine que je trouve pas la réponse a cet énoncé .

Pouvez vous m'aider ? Merci d'avance .

Bundles of wood 2007-11-19
Darcy pose la question :
When you purchase a "bundle" of wood at the store, it is marked .75 cubic feet. What is the formula for figuring out that measurement for cubic feet and what fraction of a true cord of wood (128 cubic feet) is it. I would appreciate the formula so I can build a spreadsheet to help my secretaries and myself be in compliance to the law when selling firewood. Thanks.

Parabolic Mirrors 1997-01-28
Megan Wennberg pose la question :
Consider a ray of light that passes through a chord of a parabola (the chord is above the focus and parallel to the directrix), hits the parabola at a point (x,y) and is reflected through the focus. If d1 is the distance from the chord to the point of incidence (x,y) and d2 is the distance from (x,y) to the focus, can you prove that the sum of the distances d1+d2 is constant, independent of the particular point of incidence.
Penny Nom lui répond.
