Question

Conic is represented by _____

(a) AX^2 + BY^2 + CXY + DX + EY + F = 0

(b) AX^2 + BY^2 + CXY + DX + EY = 0

(c) AX^2 + BY^2 + CXY + EY + F = 0

(d) AX^2 + BY^2 + CXY + DX = 0

The question was posed to me in an internship interview.

The origin of the question is Configuration Layout topic in portion Configuration Layout and Loft of Aircraft Design

Answer 1

Right choice is (a) AX^2 + BY^2 + CXY + DX + EY + F = 0

The explanation: A conic is a 2^nd degree curve. Conic in simple mathematical language is defined by using AX^2 + BY^2 + CXY + DX + EY + F = 0. Constants are based on our requirements. WE can produce different cross-section shape such as circle, parabola etc. by using conic.
