Pallavi Arora

Beginner-Level 5

Those who are preparing for any competive exam such as JEE Main, NDA and others really need to memorise formulas. Check the important formulas below;

Circle

Standard equation (center at origin): $x^{2} + y^{2} = r^{2}$
$x^2 + y^2 = r^2$
General form: $x^2 + y^2 + 2gx + 2fy + c = 0$
Center = (–g, –f), Radius = ?(g² + f² – c)

Parabola:

Standard form (horizontal axis): $y^{2} = 4 a x$
$y^2 = 4ax$
Standard form (vertical axis): $x^{2} = 4 a y$
$x^2 = 4ay$
Vertex: (0, 0)
Focus: (a, 0) or (0, a)
Directrix: x = –a or y = –a
Latus rectum = 4a

Ellipse: Check all the important topics related to this topic below;

Standard form (major axis along x-axis):
- $\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$ where a > b
- Eccentricity: $e = \sqrt{1 ? \frac{b^{2}}{a^{2}}}$
  $e = \sqrt{1 - \frac{b^2}{a^2}}$

Foci: (±ae, 0)
Latus rectum: $\frac{2b^2}{a}$

Hyperbola: Students can check impor

Is Conic Section Chapter is important for entrance exams like JEE, CUET and others?

0 Follower 3 Views

Himanshi Singh

Beginner-Level 5

The Conic Sections chapter is highly important for entrance exams like JEE, CUET, and NDA. Conic Section covers fundamental concepts such as parabola, ellipse, and hyperbola, along with key terms like focus, directrix, and eccentricity. Generally directly and some times application based questions are asked in JEE Main, and CUET UG.

Students must know that conic sections also form the base for advanced topics like calculus and coordinate geometry, mastering the concepts related to Circle, Parabola, Hyperbola and others are essential for both board exams and competitive success.
