Answer -
We know that f (x) = tan x is a periodic function withperiod π.
So, f (x) = tan2 (x) is a periodicfunction with period π. So, we will draw the graph of f (x) = tan2 (x)in the interval [0, π]. The values of f (x) = tan2 (x) atvarious 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) | 2 π |
| f (x) = tan2 (x) | 0 | ∞ | →∞ | 0 | ∞ | →∞ | 0 |
The required curve is:
