求导(1)y=(1-根号x)(1+1/根号x)求导(1)y=(1-根号x)(1+1/根号x)求导(1)y=(1-根号x)(1+1/根号x)y=(1-根号x)(1+1/根号x)y=(1-√x)(1+1/

求导(1)y=(1-根号x)(1+1/根号x)
求导(1)y=(1-根号x)(1+1/根号x)

求导(1)y=(1-根号x)(1+1/根号x)
y=(1-根号x)(1+1/根号x)
y=(1-√x)(1+1/√x)
y=(1-√x)(√x+1)/√x
y=(1-x)/√x
y'=[-√x+(1-x)/(2√x)]/x
y'=(-2x+1-x)/(2x√x)
y'=(1-3x)/(2x√x)
y'=(1-3x)√x/(2x^2)
