NCERT Solutions for Class 11 Maths Conic Sections: Points to Remember

We have summarised a few points to remember that Class 11 students can refer to while practising or revising.

A parabola is the locus of a point which moves in a plane such that its distance from a fixed point in the plane is always equal to its distance from a fixed straight line in the same plane.
Equation of the Parabola in its Standard Form is given by y2=4axy2=4ax.

Some Other Standard Forms of Parabola are:

	y2=4axy2=4ax	y2=−4axy2=−4ax	x2=4ayx2=4ay	y2=−4ayy2=−4ay
Coordinates of vertex	(0,0)0,0	(0,0)0,0	(0,0)0,0	(0,0)0,0
Coordinates of focus	(a,0)a,0	(−a,0)-a,0	(0,a)0,a	(0,−a)0,-a
Equation of the directrix	x=−ax=-a	x=ax=a	y=−ay=-a	y=ay=a
Equation of the axis	y=0y=0	y=0y=0	x=0x=0	x=0x=0
Length of the Latus-rectum	4a4a	4a4a	4a4a	4a4a
Focal distance of a point P(x,y)Px,y	a+xa+x	a−xa-x	a+ya+y	a−ya-y
