At the end points A,B of the fixed segment of length L, lines are drawn meeting in C and making angles `theta` and `2 theta` respectively with the given segment. Let D be the foot of the altitude CD and let x represents the length of AD.
Find the value of x as `theta` tends to zero i.e., `underset( theta rarr 0)("Lim") x`.
