Application +4 | -1

Let

y = y\left( x \right)

be the solution of the differential equation,

\frac{{2 + \sin x}}{{y + 1}}.\frac{{dy}}{{dx}} = - \cos x,y > 0,\,y\left( 0 \right) = 1

. If

y\left( \pi \right) = a

and

\frac{{dy}}{{dx}}

x = \pi

b

, then the ordered pair

\left( {a,b} \right)

is equal to

View answer and explanation

Correct option: A

\left( {1,1} \right)

The correct answer is A ((1,1)) because it is found by solving the differential equation and substituting the given conditions to find a and b.
