If the eccentricity is less than one, then conic is a __________
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.
A circle, if scaled only in one direction becomes a :
Remains as a circle
Question 2 Explanation:
A circle, if scaled only in one direction becomes a ellipse.
Ax2 + By2 + Cxy + Dx + Ey + F = 0 represents a :
None of the above
Question 3 Explanation:
Circle equations are often given in the general format of Ax2 + By2 + Cx + Dy + E = 0.
Y = 4x2 is an equation of
Question 4 Explanation:
Y = 4x2 is an equation of parabola.
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:
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.
