Differential Equations Question 331
Question: The general solution of $ x^{2}\frac{dy}{dx}=2 $ is
[AISSE 1984]
Options:
A) $ y=c+\frac{2}{x} $
B) $ y=c-\frac{2}{x} $
C) $ y=2cx $
D) $ y=c-\frac{3}{x^{2}} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \frac{dy}{dx}=\frac{2}{x^{2}} $
Therefore $ dy=\frac{2}{x^{2}}dx $ , Now integrate it.
