Bonsoir,
Exercice 1 :
A = V2
B = 1
C = A + B
D = A - B
A = C x C
1) 1) variables utilisées :
A, B, C
2) valeur variable A :
A = (V2 + 1)(V2 + 1)
A = 2 + V2 + V2 + 1
A = 3 + 2V2
3) a) A = D x D
b) A = C x D
Exercice 2 :
1) y = (2)^3 - 2
Y = 8 - 2
Y = 6
2) y = (-1)^3 - (-1)
Y = (-1) + 1
Y = 0
3) f(x) = x^3 - x
f(x) = x(x^2 - 1)
