Another Explanation (5):
সমাধান:
ধরি, \( u = 1 - \frac{x}{2} \)
তাহলে, \( \frac{du}{dx} = -\frac{1}{2} \)
সুতরাং, \( dx = -2 \, du \)
এখন,
\( \int \sqrt{1 - \frac{x}{2}} \, dx = \int \sqrt{u} \, (-2 \, du) \)
\( = -2 \int u^{\frac{1}{2}} \, du \)
\( = -2 \cdot \frac{u^{\frac{1}{2} + 1}}{\frac{1}{2} + 1} + c \)
\( = -2 \cdot \frac{u^{\frac{3}{2}}}{\frac{3}{2}} + c \)
\( = -2 \cdot \frac{2}{3} u^{\frac{3}{2}} + c \)
\( = -\frac{4}{3} u^{\frac{3}{2}} + c \)
\( = -\frac{4}{3} \left( 1 - \frac{x}{2} \right)^{\frac{3}{2}} + c \)
সুতরাং, \( \int \sqrt{1 - \frac{x}{2}} \, dx = -\frac{4}{3} \left( 1 - \frac{x}{2} \right)^{\frac{3}{2}} + c \) 🎉🎉
