Question:

Find the general solution to the following differential equation :

\(\frac{dy}{dx}\) =  -4xy, y(0) = 1

Options:

$y = \frac{1}{2x^2} + 1 $

y = \(\frac{1}{2x^2c}\)

y = \(\frac{C}{2x^2}\)

y = \(\frac{1}{2x^2+1}\)

Correct Answer:

y = \(\frac{1}{2x^2+1}\)

Explanation:

dy = -4xy2 . dx and then integrate to get : 

$y = \frac{1}{2x^2} + C $
