[hello-there]

I=S e^(1/x)/x^2 dx
=-e^(1/x)+C

nice
but how did you do it?

also how do you integrate Square troot x e^(xrootx)

 

[nikkifc]

also i got another question by its integration how do you integrate

Let u=1/x

du/dx = -1/x^2

nice
but how did you do it?

also how do you integrate Square troot x e^(xrootx)

I= S sqrt(x)e^(xsqrt(x)) dx
= S sqrt(x)e^(x^(3/2)) dx
Let u=x^(3/2):du=3/2 x^(1/2) dx
I= 2/3 S e^u du
=2/3 e^u +C
=2/3 e^(xsqrt(x)) +C
