Which is the correct fundamental period of cot inverse x?

In summary, the period of cot inverse x is the distance between two consecutive peaks or troughs of the function. It can be determined by using the formula T = 2π/b, where b is the coefficient of x in the function. The period cannot be negative and is always a positive value. The period of cot inverse x is the reciprocal of the period of its parent function, cot x, and will change as the coefficient of x is varied. A larger coefficient will result in a smaller period and vice versa.

What is the fundamental period of cot inverse x?
The book, “TRIGONOMETRY “by S.L.Loney says it is –pi/2 to +pi/2 whereas IIT MATHEMATICS by M.L.Khanna says that is 0 to pi

If f is a non one-to-one function, then, in order to define its "inverse" you must restrict it to an interval on which it is one-to-one. Which such interval you choose is a matter of convention. And for tangent, those are two commonly used conventions.

What is the period of cot inverse x?

The period of cot inverse x is the length of the interval over which the function repeats itself. In other words, it is the distance between two consecutive peaks or troughs of the function.

How do you determine the period of cot inverse x?

The period of cot inverse x can be determined by finding the horizontal distance between two consecutive points where the function reaches the same value. This can be done by using the formula for the period of a function: T = 2π/b, where b is the coefficient of x in the function.

Can the period of cot inverse x be negative?

No, the period of cot inverse x cannot be negative. It is always a positive value, representing the distance between two consecutive peaks or troughs of the function.

What is the relationship between the period of cot inverse x and the period of its parent function?

The period of cot inverse x is the reciprocal of the period of its parent function, cot x. This means that the period of cot inverse x will be shorter than the period of cot x, as the two functions are inverses of each other.

How does the period of cot inverse x change when the coefficient of x is varied?

As the coefficient of x is varied, the period of cot inverse x will also change. Specifically, the period will decrease as the coefficient increases, and increase as the coefficient decreases. This can be seen by the formula T = 2π/b, where a larger coefficient will result in a smaller period and vice versa.
