判定y=sin(x/2)+sin(x/5)是周期函数吗
判定y=sin(x/2)+sin(x/5)是周期函数吗
判定y=sin(x/2)+sin(x/5)是周期函数吗
是周期函数,
其周期应为 ,
函数y=sin(x/2) 与函数y=sin(x/5)两个函数周期的公倍数!
判定y=sin(x/2)+sin(x/5)是周期函数吗
y=[sin^2(x)]*[sin^2(x)]求导
一道三角恒等式证明题请证明sin(x+y)sin(x-y)=sin^2(x)-sin^2(y)
y=(sin x + COS x)^2
求证sin²x-sin²y=sin(x+y)sin(x-y)
求y=sin[sin(x^2)]的导数
3sin^2x+-2sin^2y=2sinx sin^2x+-sin^2y=?
y=12sin(2x+π/6)+5sin(π/3-2x)最大值
y=12sin(2x+π/6)+5sin(π/3-2x)的最大值
y=3sin(2x+10)+5sin(2x+70)最大值
函数y=sinx+2sin^3 x+3sin^5 x的最小正周期
matlab中一些新手问题,syms x y;y =ezplot('1/5*(-2-5/(-125+100*sin(x))*(-20*sin(x)+40+10*(-121*sin(x)^2-100*sin(x)+121+100*sin(x)^3)^(1/2))+5/2*sin(x)/(-125+100*sin(x))*(-20*sin(x)+40+10*(-121*sin(x)^2-100*sin(x)+121+100*sin(x)^3)^(1/2)))*cos(x)
sin(x+y)sin(x-y)=k,求cos^2x-cos^2y
证明sin(x+y)sin(x-y)=sinx-siny
y =sin(2x-1)求导!
y=sin(2x+a)(0
y=|sin 2x| 周期
y=e^[(sin^2)x]求导!
