解答
f(x)=2sin(x+π/6)-2cosx
=2(√3/2 sinx+1/2 cosx)-2cosx
=√3 sinx-cosx
=2sin(x-π/6)
所以最大值=2
推荐
函数y=2sin2x+2cosx-3的最大值是( ) A.-1 B.12 C.-12 D.-5
函数f(x)=2sin*2x+2cosx-5的最大值
函数f(x)=-2sin²x+2cosx的最大值和最小值
已知函数f(x)=2sin(x+π6)-2cosx. (Ⅰ)若sinx=4/5,x∈[π2,π],求函数f(x)的值; (Ⅱ)求函数f(x)的最小正周期和值域.
求下列函数的最大值、最小值,并求使函数取得最大值最小值的x的集合 (1)y=3-2cosx (2)y=2sin(1/2x-π/4
