\[y= \frac{\sqrt{1+x}}{\sqrt{x1}e^x}\int \frac{\sqrt{x1}e^x}{\sqrt{1+x}}(\frac{\sqrt{1x^2}}{1x})dx\]\[=\frac{\sqrt{1+x}}{\sqrt{x1}e^x}\int \frac{\sqrt{(1x)(1x)}e^x}{1x}dx\]\[=\frac{\sqrt{1+x}}{\sqrt{x1}e^x}\int e^xdx\]\[=\frac{\sqrt{1+x}}{\sqrt{x1}e^x}( e^x+C)\]\[=\frac{\sqrt{1+x}}{\sqrt{x1}}+\frac{C\sqrt{1+x}}{\sqrt{x1}e^x}\] Oh.. I don't know how to do it :(
