Answer 1

问：求导 y=((x-1)^3(x-5))/([3](x+1))

答：亲您好，很高兴为您解答，y=(x-1)(x-3)^2 导数为=（x-3）^2+2*(x-1)(x-3

问：求导 y＝(x－1)³×√x-5╱³√(2x+1)

答：y=(x-1)*x^(2/3)则y'=1*x^(2/3)+(x-1)*x^(-1/3)=2x^(2/3)-x^(-1/3)=x^(-1/3)*(2x-1)则x<0时,x^(-1/3)<0,2x-1000,2x-1<0,y'1/2,显然y'>0所以x<0，单调递增01/2，单调递增x=0。极大值是0x=1/2，极小值是-1/2*³(1/4)
