解答
即2π/k+2π/k=3π/2
所以k=8/3
所以
f(x)=asin(8x/3+π/3)
φ(x)=bcos(8x/3-π/3)+2011
推荐
- 设有函数f(x)=asin(kx-π/3)和函数g(x)=bcos(2kx-π/6),(a>0,b>0,k>o),若它们的最小正周期之和
- 已知函数f(x)=asin(πx+α﹚+bcos(πx+β﹚+4,且f(2004)=3,则f(2011)=__
- 已知函数f(x)=asin(πx+α)+bcos(πx+β)+4,x∈R,且f(2011)=3,则求f(2012)的值
- 设f(x)=asin(πx+α)+bcos(πx+β),其中a,b,α,β都是非零实数,若f(2010)=-1,则f(2011)=_.
- 已知函数f(x)=asin(kx+π/3)和φ(x)=btan(kx-π/3),k>0
