把函数f(x)=sin(7π/8-x)*cos(x+π/8)的图象向右平移a(a>0)的单位,得函数g(x)图象,且g(X)图象且g(X)图象关于直线x=π/4对称(1)求a的最小值(2)已知当x∈[(2b+1)π/8,(3b+2)π/8](b∈N)时,过函数f(x)图象上任意两点

判断下列函数的奇偶性 f(x)=[sin(π/2+x)cos(π/2-x)tan(-x+3π)]/[sin(7π-x)tan(8π-x)] 已知函数f(x)=sin(x+π/6)cos(x+π/6)如何把这种函数化简 设函数 f(x)=sin(2x+y),(-π 设函数f(x)=sin(2x+φ)(-π 设函数f(x)=sin(2x+φ)(-π 设函数f x=SIN(2X+φ)(-π 设函数f(x)=sin(2x+φ)(-π 设函数f(x)=sin(2x+φ)(-π 已知函数F(X)=SIN(2X+φ)(-π 已知函数f(x)=cos2x/[sin(π/4-x)] 设函数f(x)=sin(2x+φ)(-π 设函数f(x)=sin(2x+φ)(-π 设函数f(x)=sin(2x+ φ)(-π 如果函数f(x)=sin(πx+a)(0 函数f(x)=sin(πx²)(-1 设函数f(x)=sin(2x+φ)(-π 函数f(x)=sin(2x+a) -π 如果函数f(x)=sin(π x+A)(0
