The general solution of the equation dydx = y2 - x2yx + 1 is
y2 = (1 + x)log(1 + x) - c
y2 = 1 + xlogc1 - x - 1
y2 = 1 - xlogc1 - x - 1
y2 = 1 + xlogc1 + x - 1
The general solution of the differential equation dydx + sinx + y2 = sinx - y2 is
logetany2 = - 2sinx2 + C
logetany4 = 2sinx2 + C
logetany4 = - 2sinx2 + C

The function y specified implicitly by the relation ∫0yetdt + ∫0xcostdt = 0 satisfies the differential equation
e2yd2ydx2 + dydx2 = sinx
eyd2ydx2 + dydx2 = sin2x
ey2d2ydx2 + dydx2 = sinx
eyd2ydx2 + dydx2 = sinx
D.
Given,∫0yetdt + ∫0xcostdt⇒ et0y + sinx0x = 0⇒ ey + sinx = 0By differentiating w.r.t. 'x', we get eydydx + cosx = 0Again, by differentiating w.r.t. 'x', we geteydydx . dydx + eyd2ydx2 - sinx = 0⇒ eyd2ydx2 + dydx2 = sinx
