MCQ
$y' = \frac{{y + 1}}{{x - 1}},\,y(1) = 2$ નો ઉકેલની સંખ્યા મેળવો.
- ✓એકપણ નહી.
- Bએક
- Cબે
- Dઅનંત
Integrating both sides, $\int {\frac{{dy}}{{y + 1}} = \int {\frac{{dx}}{{x - 1}}} } $
==> $\log (y + 1) = \log (x - 1) + \log c$ ==> $(y + 1) = (x - 1)c$
At $x = 1$ ==> $y = - 1$ where as $y(1) = 2$
Hence, the solution is not possible.
