What does your textbook say about 4.8.1 The graph of the cotangent function?
The cotangent function is continuous on the set \ ) { } . Let us first draw the graph of cotangent function in \ ) { } . In the first and third quadrants, the cotangent function takes only positive values and in the second and fourth quadrants, it takes only negative values. The cotangent function has no maximum value and no minimum value. The cotangent function falls from ¥ to for x ∈ , π ; falls from to −∞ for x ∈ π π , ; falls from ¥ to for x ∈ and falls from to −∞ for x ∈
