exercice n=°52 p: 78
1)nafrid anna f zawjia
g(x) = f(x) +f(-x) /2
g(x)=2f(x)/2
g(x)=f(x) wa minhou g zawjia
*h(x)=f(x)-f(-x)/2
h(x)=f(x)-f(x)/2
h(x)=0 wa minhouh fardia wa zawjia
2) nafrid f fardia -f(x)=f(-x) wa minhou:
g(x)=f(x)-f(x)/2
g(x)=0
idan g fardia wa zawjia
h(x)=f(x)+f(x)/2
h(x)=2f(x)/2
h(x)=f(x) wa minhou
h fardia
