Webb解:(1)f(x)=a·b=m(1+sin2x)+cos2x由于f(x)图象经过点(,2).∴f()=2,即m(1+sin)+cos=2,∴m=1.(2)由(1)得f(x)=1+sin2x+cos2x=1+sin(2x+).故当sin(2x+)=-1时,f(x)取得最小值,f(x)min=1-.相应的2x+=π+2kπ,k∈Z,∴x=kπ+π,k∈Z,∴使函数f(x)取得最小值的x的集合为{x x=kπ+π,k∈Z}.⏺人教B版必修4同步练习同步测控 WebbSolve your math problems using our free math solver with step-by-step solutions.
