( y=sqrt{x}+frac{1}{sqrt{x}} ) ( frac{d y}{d x}=frac{1}{2 sqrt{x}}+left(-frac{1}{2 x sqrt{x}}right) ) ( frac{d y}{d x}=frac{1}{2 sqrt{x}}-frac{1}{2 x sqrt{x}} ) ( frac{d y}{d x}=frac{x-1}{2 x sqrt{2}} ) mentiply this by ( 2 x ) ( 2 x frac{d y}{d x}=frac{x-1}{sqrt{x}} ) ( Rightarrow A T G, frac{x-1}{sqrt{x}+sqrt{x}+frac{1}{sqrt{7}}}= ) ( A T Q_{1} Rightarrow frac{x-1+x+1}{sqrt{x}} Rightarrow frac{2 x}{sqrt{x}} Rightarrow 2 sqrt{x} )
