$$\frac{d}{dx}(\sqrt{1-x}+\sqrt{x-2})$$

Commented by i jagooll last updated on 09/May/20

$$=\frac{-1}{2\sqrt{1-\mathrm{x}}}+\frac{1}{2\sqrt{\mathrm{x}-2}}$$$$=\frac{1}{2}\{\frac{1}{\sqrt{\mathrm{x}-2}}-\frac{1}{\sqrt{1-\mathrm{x}}}\}$$$$=\frac{1}{2}\left\{\frac{\sqrt{1-\mathrm{x}}-\sqrt{\mathrm{x}-2}}{\sqrt{3\mathrm{x}-{\mathrm{x}}^2-2}}\right\}$$
