What does the equation x d y d x -2 y=0 represent?
Options
- AA family of straight lines
- BA family of circles
- CA family of parabolas
- DA family of ellipses
Correct answer
C. A family of parabolas
Step-by-step solution
aligned & x d y d x -2 y=0 & x d y d x =2 y aligned 1 y dy =2 1 x dx aligned & ny =2 x+ nc & ny = nx ^2+ nc & n y= n ( cx ^2 ) & y = cx ^2 aligned It represent the equation of parabolas.
