Question -
Answer -
We know that f (x) = sec x is a periodic function with period π.
So, f (x) = 3 sec (x) is a periodic function with period π. So, we will draw the graph of f (x) = 3 sec (x) in the interval [0, π]. The values of f (x) = 3 sec (x) at various points in [0, π] are listed in the following table:
| x | 0 (A) | π/2 (B) | -π/2 (C) | π (D) | -3π/2 (E) | 3π/2 (F) | 2π (G) | 5π/2 (H) |
| f (x) = sec x | 3 | ∞ | -∞ | -3 | -∞ | ∞ | 3 | ∞ |
The required curve is:
