1.y=sin(-X+π/6)2.y=cos(-2X+π/3) C语言求三角函数f(x,y,z)=sin(x)/(sin(x-y)*sin(x-z))+sin(y)/(sin(y-x)*sin(y-z))+sin(z)/(sin(z-x)*sin(z-y))代码#include #include double fun(double x,double y,double z){double a,b,c,sum;a=sin(x)/(sin(x-y)*sin(x-z));b=sin(y)/(sin(y-x)*sin(y-z));c 判断单调性 y=sin(x-π/6) y=sin(-2x+π/3) 1.y=x*e^(2x) 2.y=(sin(2x))/x 3.y=sin(3x+(π/3))怎么求导数! Mathematica y''+ sin(x) y=x 求证sin²x-sin²y=sin(x+y)sin(x-y) 1.已知函数y=Asin(ωx+φ)在同一周期内,当x=π(派）/12时,ymax=2,当y=7π/12时,ymin=-2,那么函数的解析式为（ ）.A.y=2sin(2x+π/3) B.y=2sin(2x-π/6) C.y=2sin(2x+π/6) D.y=2sin(2x-π/3) 2.已知1=sin(2π/3+φ),那么φ=?3.函数y= 求单调递增区间：1.y=log2[sin(x+π/6)]2.y=根号下sin(2x-π/3)要过程,非常感谢. 已知x+y+z=π,证明sin(x+y)+sin(y+z)+sin(z+x)≥sin2x+sin2y+sin2z 证明sin(x+y)sin(x-y)=sinx-siny 基本函数的导函数.念法.1.y=c(c为常数) y'=0 2.y=x^n y'=nx^(n-1) 3.y=a^x y'=a^xlna y=e^x y'=e^x 4.y=logax y'=logae/x y=lnx y'=1/x 5.y=sinx y'=cosx 6.y=cosx y'=-sinx 7.y=tanx y'=1/cos^2x 8.y=cotx y'=-1/sin^2x 9.y=arcsinx y'=1/√1-x^2 10.y=a 给定性质①最小正周期为π②图象关于x=π/3对称,则下列四个函数中同时具有性质①②的是()A.y=|sin(x)| B.y=sin(x/2+π/3) C.y=sin(2x-π/6) D.y=sin(π/3-2x)+sin(2x) y=sin(x+π/3)周期 y=|sinπx|的周期 y=sin根号x y=sinx+sin|x| 下列函数中最小正周期是π且图像关于直线x=π/3对称的是 a y=.y=sin(2x+6）B y=sin(x/2+π/6)C y=sin(2x-π/6) D y=sin(2x-π/3) (y')^2 = y^4 - y^2答案是y(x) = 1/sin(∏/6±x),恒为0的不算 其实是通解啦y(x) = C/sin(∏/6±x),C为常数
