f(2+x)+f(x-6)=0怎么变成周期函数?
令t=2+x之后变成
f(t)=-f(8-t)
之后怎么办?

解答
f(x+2)=-f(x-6)
f(x+8)=-f(x)
f(x+16)=-f(x+8)=f(x)
T=16
推荐
函数f(x)是以2为周期的函数,且f(2)=2,则f(6)=_.
函数f(x)是以2为周期的函数,且f(2)=2,则f(6)=_.
设函数f(x)=3sin(wx+π/6),w>0,x属于R,且以π/2为最小正周期 (1)求f(0)? (2)求f(x)的解析式?
设函数f(x)=asinwx+bcoswx(w>0)已知函数f(x)的最小正周期为π,且当x=π/6时
已知函数f(x)=4cosxsin(x+π/6)-1 (1)求函数fx的最小正周期 (2)求fx的、在区间{-π/6,π/4}上的
两数和为3,积为-10 求这两个数
