回答1:

(x-1)/(x^0.5) =x/(x^0.5)-1/ (x^0.5)=x^0.5-1/(x^0.5)
x^0.5原函数是2/3*x^1.5+C
1/(x^0.5)原函数是2*x^0.5+C
所以(x-1)/(x^0.5) 原函数是2/3*x^1.5-2*x^0.5+C

回答2:

解:(x-1)/x^0.5=√x-1/√x=x^(1/2)-x^(-1/2)
∴(x-1)/x^0.5的原函数是
(2/3)x^(3/2)-2√x+C

导数为(x-1)/√x 求原函数
解:原函数f(x)=∫[(x-1)/√x]dx
令√x=u,则x=u²,dx=2udu,于是f(x)=∫[(x-1)/√x]dx=2∫[u²-1)/u]udu=2∫(u²-1)du
=2[(u³/3)-u]+C=(2/3)x^(3/2)-2√x+C.
