SUMMARY
The fundamental period of cot inverse x is a topic of debate, with two primary conventions presented in literature. S.L. Loney's "TRIGONOMETRY" states the period as -π/2 to +π/2, while M.L. Khanna's "IIT MATHEMATICS" claims it is 0 to π. The choice of interval is essential for defining the inverse of a non one-to-one function, and the selection of the interval is largely a matter of convention. For examination purposes, understanding both conventions is crucial.
