Question

The rate of activity of a person y with age t is given by (1+t) $\frac{dy}{dx}=e^{-y}-1$. For the initial condition y = 1 at r = 0, the dy dt solution is given by,

• A. $y=in(\frac{1}{t+1})$
• B. $y=in(\frac{e}{t+1})$
• C. $y=in(\frac{e+t}{t+1})$
• D. $y=in(\frac{e-t}{t+1})$

Answer 1

Answer: (C)

$y=in(\frac{e+t}{t+1})$

Answer 2

The correct option is(C): $y=in(\frac{e+t}{t+1})$
