Differential Equations
Evaluate : ylog y dx - xdy = 0

a) Y = e
b) Y = e^x
c) Y = e^cx
d) None of these


✔Answer
Correct Answer Is : Y = e^cx
Solution Is :
Evaluate: cos(dy/dx) = a(a Є R); y = 1 when x = 0.

a) Cos(y - 1) = a
b) Cos(y - 1/x) = a
c) Cos(y + 1/x) = a
d) Cos(y + 1) = a


✔Answer
Correct Answer Is : Cos(y - 1/x) = a
Solution Is :
Find the equation of a curve passing through the point (0 , 0) and whose differential equation is y` = e^ sin x.

a) 2y - 1 = e^x (sin x - cos x)
b) 2y - 1 = e^x (sin x + cos x)
c) 2y - 1 = e^x
d) 2y + 1 = e^x (sin x - cos x)


✔Answer
Correct Answer Is : 2y - 1 = e^x (sin x - cos x)
Solution Is :
