A) parabola whose vertex is at origin
B) Circle whose centre is at origin
C) A rectangular hyperbola
D) Straight line passing through origin
Correct Answer: D
Solution :
[d] We have \[x\,dy=y\,dx\] \[\frac{dy}{y}=\frac{\,dx}{x}\] integrate both side, we get \[\log \text{ }y=\log x+\log C\] \[\log \text{ }y=\log xC\] \[y=xC\], straight line passes through (0, 0)You need to login to perform this action.
