What should be the correct range of acot function
As in the book, the range of acot(x) is 0 to pi

But when I check in HP prime by plotting acot(x) function, the range is -pi/2 to pi/2

Also, in wolfram alpha, the range is -pi/2 to pi/2

In TI-Nspire, the range is 0 to pi

What should be the correct one?
