Domain of \( \arcsin(x) \) and \( \arccos(x) \): \([-1, 1]\) Domain of \( \arctan(x) \) and \( \arccot(x) \): All real numbers (\(\mathbb{R}\)) Range of \( \arcsin(x) \): \([-\frac{\pi}{2}, \frac{\pi}{2}]\) Range of \( \arccos(x) \): \([0, \pi]\) Graphical Characteristics and Symmetry The graphical representation of inverse trigonometric functions reveals their relationship with their original counterparts through reflection across the line \(y = x\). For the inverse sine, the domain is limited to the interval \([-1, 1]\) with a principal range of \([-\frac{\pi}{2}, \frac{\pi}{2}]\).
Understanding Graph Behavior of Inverse Trigonometric Functions
The derivative of the inverse tangent yields the familiar \(\frac{1}{1+x^2}\), a result that appears frequently in integral calculus. In contrast, the inverse cosine graph is strictly decreasing and lacks origin symmetry, classifying it as a neither odd nor even function.
The graph of the inverse sine forms a continuous, increasing curve that passes through the origin, visually demonstrating its odd function property where \(f(-x) = -f(x)\). Conversely, the inverse tangent accepts all real numbers as input, producing outputs within \((-\frac{\pi}{2}, \frac{\pi}{2})\), while the inverse cotangent uses the range \((0, \pi)\) to avoid ambiguity in calculation.
Understanding Graph Behavior of Inverse Trigonometric Functions
Similarly, composing an inverse function with its trigonometric counterpart yields the angle itself, expressed as \(\arcsin(\sin(x)) = x\) when \(x\) lies within the defined principal range. The derivative of the inverse sine is \(\frac{1}{\sqrt{1-x^2}}\), while the derivative of the inverse cosine is its negative counterpart, \(-\frac{1}{\sqrt{1-x^2}}\).
