1. The problem statement, all variables and given/known data
function f:R>R can be written as a sum f=f1+f2 where f1 is even and f2 is odd。show that if f is continuous then f1 and f2 may be chosen continuous, and if f is differentiable then f1 and f2 can be chosen differentiable 2. The attempt at a solution i have try some examples, but i still cannot get the idea from that

Given function f, let [itex]f_e(x)= (f(x)+ f(x))/2[/itex] and [itex]f_o(x)= (f(x) f(x))/2[/itex].
