求导y-sinx-cos(x-y)=0求导y-sinx-cos(x-y)=0求导y-sinx-cos(x-y)=0对x求导有y''-cosx+sin(x-y)(-y'')=0整理有y''=cosx/(1-s

求导y-sinx-cos(x-y)=0
求导y-sinx-cos(x-y)=0

求导y-sinx-cos(x-y)=0
对x求导有
y'-cosx+sin(x-y)(-y')=0
整理有y' = cosx/( 1-sin(x-y) )

求导y-sinx-cos(x-y)=0 y=(sinx)^x(sinx>0) 求导 y=cos根号下x+根号下sinx求导求导y=x/sinx+sinx/x y=（tanx）^sinx 求导y=e^sinx*cos(sinx) 求导 y=(1+sinx)/cosx,求导是不是等于（sinx+1）/(cos^2)x 求导 y=(x+cosx)/(x+sinx) y=x+(sinx)^x求导 y=(x/1+x)^sinx求导 y=e^x(cosx+sinx)求导 y=x sinx-cosx求导 y=sinx/1+3x求导 y=(x+sinx)tanx 求导求导 y=(-2x+3)sinx y=sinx/2x 求导求导,y=(1-x^2)/sinx 求导 y=x的平方+sinx 求导 y=2x*sinx
