The tan function has several distinctive properties that are crucial for understanding its behavior and applications. Here are some of its essential properties:
1)Periodicity: The tan function is periodic with a period of π, which means it repeats its value every π units. This is expressed as tan(θ+π) = tan(θ) for any angle θ.
2)Domain: The domain of the tan function includes all real numbers except odd multiples of π/2, where tan(θ) would be undefined due to division by zero. Thus, θ ≠ ±π/2, ±3π/2, ±5π/2,...
3)Range: The range of the tan function is all real numbers, which means output of the tan function is between -∞ and ∞. Thus, -∞ < tan(θ) < ∞.
4)Symmetry: The tan function is an odd function, which means that tan(-θ) = -tan(θ). This property implies that the tan function has rotational symmetry about the origin.
5)Asymptotes: The tan function has vertical asymptotes at odd multiples of π/2. This means that tan(θ) is undefined at θ = π/2 ± nπ for integers.
