Question -
Answer -
We know that f (x) = cot x is a periodic function with period π.
So, f (x) = cot (2x) is a periodic function with period π. So, we will draw the graph of f (x) = cot (2x) in the interval [0, π]. The values of f (x) = cot (2x) at various points in [0, π] are listed in the following table:
| x | 0 (A) | π/4 (B) | -π/2 (C) | π/2 (D) | 3π/4 (E) | -π (F) |
| f (x) = cot x | →∞ | 0 | -∞ | →∞ | 0 | -∞ |
The required curve is:
