设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
f(x)=sin(wx+φ)+cos(wx+φ)
=√2sin(wx+φ+π/4)
T=2π/w=π
w=2
f(x)=√2sin(2x+φ+π/4)
f(-x)=f(x),
所以 f(-π/8)=f(π/8)
sinφ=sin(π/2+φ)=cosφ
tanφ=1
|φ|
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
老师好：设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
设函数f(x)=sin(wx+φ)+cos(wx+φ)(w>0,|φ|
设函数f(x)=sin(wx+t)(-π/2
设函数f(x)=sin(wx+t)(-π/2
设函数f(x)=sin(wx+g)+cos(wx+g) (w>0,|g|
设函数f(x)=sin(wx+q)+cos(wx+q)(w>0,q的绝对值
设函数f（x）=sin（wx+φ）（w>0,-π/2
函数f(x)=sin(wx+φ)(w>0,|φ|
函数f(x)=sin(wx+φ)(w>0,|φ|
函数f(X)=sin(wx+φ)(w>0,|φ|
已知函数f(x)=sin(wx+φ)(w
已知函数f(x)=sin(wx+φ)(w
已知函数f(x)=sin(wx+φ)(w
