### Common Errors in Secondary Mathematics

Common Errors Committed  by the  Students  in Secondary Mathematics   Errors  that students often make in doing secondary mathematics  during their practice and during the examinations  and their remedial measures are well explained here stp by step.  Some Common Errors in Mathematics

### Conic Sections /Circle & Parabola/Chapter-11/Class-XI CONIC SECTION The sections of the double napped right circular cone with the plane are called conic sections. eg:- circle, ellipse, parabola and hyperbola etc. all are the examples of conic sections. APPLICATIONS:- These curves have wide applications in the field of planetary motion, design of telescope, antenas, reflectors of flash light and automobile headlights. Vertex of the double napped cone separate the cone into two parts each part is called Nappes. α (alpha) is the angle made by the generator with the x-axis. Maths Conic Section Part 1 Class 11 NCERT-cbse mathematics DIFFERENT TYPES OF CONIC SECTIONS:- CIRCLE:-   When β(beta) = 90, then intersection of cone with plane is called circle. ELLIPSE:- When α<β<90 then intersection of plane and cone gives an ellipse. PARABOLA:- When α= β then intersection of plane and cone gives parabola. HYPERBOLA:- When 0<β<α then the intersection of plane and cone gives a hyperbola. Maths Conic
