已知函数fx=Asin(2x+5π/6)(A>0.x∈R)的最小值为-2求f0

问题描述:

已知函数fx=Asin(2x+5π/6)(A>0.x∈R)的最小值为-2求f0
已知函数fx=Asin(2x+5π/6)(A>0.x∈R)的最小值为-2求f0 2.若函数fx的图象向左平移fine(fine>0个长度,得到的曲线关于y轴对称,求fime最小值

1、∵函数fx=Asin(2x+5π/6)(A>0.x∈R)的最小值为-2∴A=2即f(x)=2sin(2x+5π/6)则f(0)=2sin(5π/6)=12、f(x)=2sin(2x+5π/6)=2sin(2x+5π/6-2π)=2sin(2x-7π/6)=2sin(2x-2π/3-π/2)=-2cos(2x-2π/3)=-2cos2(x-π/...
