化y=sin^22x+2√3sin2xcos2x+3cos^22x
最小正周期,和单调递增区间。
化y=sin^22x+2√3sin2xcos2x+3cos^22x最小正周期,和单调递增区间。
y=sin^22x+2√3sin2xcos2x+3cos^22x
=(sin2x+√3cos2x)^2
=4*(1/2*sin2x+√3/2*cos2x)^2
=4*(sin(2x+pi/6))^2
y=sin^22x+2√3sin2xcos2x+3cos^22x
=(sin2x+√3cos2x)^2
=4(1/2*sin2x+√3/2cos2x)^2
=4(cos(π/3)*sin2x+sin(π/3)*cos2x)^2
=4*(sin(2x+π/3))^2
