Soit ABC un triangle rectangle en A et soit H le pied de la hauteur issue de A.
1) Ecrivez la relation entre AH, BH
et CH.
A𝐇 𝟐=BH×CH
.
2) En prenant BH=x et CH=
1
𝑥
et en
imposant au triangle ABC d’être toujours
rectangle en A, complétez le tableau ci-
contre.
• Quelle est, lorsque x tends vers +ꝏ, la limite
de 𝐀𝐇 𝟐 ? 𝐥𝐢𝐦
𝒙→+∞
𝑨𝑯 𝟐
= 𝟏
A𝐇 𝟐=BH×CH
1
∞ 0
𝑨𝑯 𝟐 = 𝑩𝑯 × 𝑪𝑯
En passant à la
limite
1 = 0 × +ꝏ
3) En prenant BH= x et CH =
𝟏
𝒙 𝟐 et en imposant au triangle ABC d’être rectangle en A,
complétez le tableau ci-dessous.
𝐥𝐢𝐦
𝒙→+∞
𝑨𝑯 𝟐
= 𝟎
𝑨𝑯 𝟐 = 𝑩𝑯 × 𝑪𝑯
En passant à la
limite
0 = 0 × +ꝏ
4) En prenant BH= 𝒙 𝟐
et CH =
𝟏
𝒙
et en imposant au triangle ABC d’être
toujours rectangle en A, Complétez le tableau suivant:
𝐥𝐢𝐦
𝒙→+∞
𝑨𝑯 𝟐
= +∞
𝑨𝑯 𝟐
= 𝑩𝑯 × 𝑪𝑯
En passant à la
limite
+ꝏ = 0 × +ꝏ
0× ꝏ = ꝏ 0× ꝏ = 0 0 × ꝏ = 1
Donc on a trouvé 3 cas +ꝏ= 0× +ꝏ , 0=0× +ꝏ et 1= 0× +ꝏ /que
peut-on conclure?
Le produit d’une fonction qui tend vers +ꝏ et d’une fonction qui tend vers 0 est une
fonction qui peut tendre vers 0, +ꝏ ou vers un nombre a≠0. C’est ce qu’on appellee
une forme indéterminée.
