Study Notes
Inverse Trigonometric Functions
- Inverse sine function (arcsin x) is defined as y = arcsin x if and only if sin y = x, where -1 ≤ x ≤ 1 and -π/2 ≤ y ≤ π/2. The domain of y = arcsin x is [-1, 1] and the range is [-π/2, π/2].
- Inverse cosine function (arccos x) is defined as y = arccos x if and only if cos y = x, where -1 ≤ x ≤ 1 and 0 ≤ y ≤ π. The domain of y = arccos x is [-1, 1] and the range is [0, π].
- Inverse tangent function (arctan x) is defined as y = arctan x if and only if tan y = x, where x is any real number and -π/2 < y < π/2. The domain of y = arctan x is (-∞, ∞) and the range is (-π/2, π/2).
- The graphs of inverse trigonometric functions are specific sections of the corresponding trigonometric functions' graphs, reflecting the restricted domains.
Inverse Trigonometric Properties
- sin(arcsin x) = x, for -1 ≤ x ≤ 1 and -π/2 ≤ y ≤ π/2
- arcsin(sin y) = y, for -π/2 ≤ y ≤ π/2
- cos(arccos x) = x for -1 ≤ x ≤ 1 and 0 ≤ y ≤ π
- arccos(cos y) = y for 0 ≤ y ≤ π
- tan(arctan x) = x for all real numbers x, and -π/2 < y < π/2
- arctan(tan y) = y for -π/2 < y < π/2
Inverse Trigonometric Functions Definition
- These functions are used to find the angle associated with a given trigonometric ratio.
- The basic domains and ranges for arcsine, arccosine, and arctangent functions are crucial for understanding their limitations.
- For arcsin, the input is a sine ratio, and the output is the angle which the sine ratio corresponds to. Input values are between -1 and +1, output values are in quadrant 1 and 4 of the unit circle.
- For arccos, the input is a cosine ratio, and the output is the angle. Input values are between -1 and +1, output values are in quadrant 1 and 2 of the unit circle.
- For arctan, the input is a tangent ratio, and the output is the angle. Input values are all real numbers, and, output values are in quadrant 1 and 4 of the unit circle.
Evaluating Specific Values
- Exact values of inverse trigonometric functions can be found using knowledge of the unit circle.
