Question 1 |

If the eccentricity is less than one, then conic is a __________

Circle | |

Parabola | |

Ellipse | |

Hyperbola |

Question 1 Explanation:

**If the eccentricity**is zero, the curve is a circle;

**if**equal to

**one**, a parabola;

**if less than one**,

**an**ellipse; and

**if**greater

**than one**, a hyperbola.

Question 2 |

A circle, if scaled only in one direction becomes a :

Ellipse | |

Parabola | |

Hyperbola | |

Remains as a circle |

Question 2 Explanation:

A circle, if scaled only in one direction becomes a ellipse.

Question 3 |

Ax

^{2}+ By^{2}+ Cxy + Dx + Ey + F = 0 represents a :Line | |

Conic section | |

Circle | |

None of the above |

Question 3 Explanation:

Circle equations are often given in the general format of Ax

^{2}+ By^{2}+ Cx + Dy + E = 0.Question 4 |

Y = 4x^{2} is an equation of

Parabola
| |

Circle | |

Hyperbola
| |

Eclipse |

Question 4 Explanation:

Y = 4x

^{2}is an equation of parabola.Question 5 |

Consider a triangle A(0,0), B(1,1) and C(5,2). The triangle has to be rotated by an angle of 45 about the point P(-1, -1). What shall be the coordinates of the new triangle?

Question 5 Explanation:

Question 6 |

Which of the following statement(s) is/are incorrect ?

Mapping the coordinates of the points and lines that form the picture into the appropriate coordinates on the device or workstation is known as viewing transformation. | |

The coordinate system that corresponds to the device or workstation where the image is to be displayed is known as physical device coordinate system | |

The right-handed cartesian coordinates system in whose coordinates we describe the picture is known as world coordinate system. | |

Left - handed coordinate system in which the display area of the virtual display device corresponds to the unit (|x|) square whose lower left-hand corner is at the origin of the coordinate system, is known as normalized device coordinate system. |
