解答
f(x)=√3sinωx+cosωx
=2(sinωx*√3/2+cosωx*1/2)
=2(sinωx*cosπ/6+cosωx*sinπ/6)
=2sin(ωx+π/6)
推荐
已知函数f(x)=2sin(x/4)cos(x/4)-2根号3sin方(x/4)+根号3
已知函数f(x)=2根号3sin^(2x/2)+2sin(x/2)cos(x/2)-根号3
已知函数f(x)=2根号3sin(x/2+派/4)cos(x/2+派/4)-sin(x+派).求f(x)的最小正周期
已知函数f(X)=2sin(x-π/3)cos(x-π/3)+2根号3cos^2(x-π/3)-根号3,若函数y=f(2x)-a在区间
已知函数f(x)=3ωx+cos(ωx+π3)+cos(ωx-π3),x∈R,(其中ω>0). (1)求函数f(x)的值域; (2)若函数f(x)的最小正周期为π2,则当x∈[0,π2]时,求f(x)的单调递减区间.
