MCQ
સમીકરણ $\frac{{dy}}{{dx}} = {e^{x - y}} + {x^2}{e^{ - y}}$ નો ઉકેલ મેળવો.
- ✓${e^y} = {e^x} + \frac{{{x^3}}}{3} + c$
- B${e^y} = {e^x} + 2x + c$
- C${e^y} = {e^x} + {x^3} + c$
- D$y = {e^x} + c$
==> ${e^y}dy = ({x^2} + {e^x})dx$
Now integrating both sides, we get ${e^y} = \frac{{{x^3}}}{3} + {e^x} + c$.
