Question

The polar coordinates of strophoid is given by

(a) ±\sqrt{(f(θ)cosθ-a)^2+(f(θ)sinθ-b)^2}. \)

(b) False

(c) True

I got this question in an interview.

This intriguing question originated from Standard Curves in Cartesian Form in division Curve Tracing of Engineering Mathematics

Answer 1

The correct option is (b) False

For explanation: The strophoid is a special case of cissoid and is usually defined as a looping curve. It was first studied by Issac Barrow (October 1630 – 4 May 1677) in 1670.
