Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry. For a circle of radius 1, arcsin and arccos are the lengths of actual arcs determined by the quantities in …

Enter the sine value, select degrees (°) or radians (rad) and press the = button.

Arcsin is one of the six main inverse trigonometric functions. It is the inverse trigonometric function of the sine function. Arcsin is also called inverse sine and is mathematically written as arcsin x or sin -1 x …

Online arcsine calculation tool with output in degrees or radians. Supports input of decimal numbers (0.5, 6, -1, etc.) and fractions (1/4, 2/3, 4/3, 1/3 etc.).

While we can find the value of arcsine for any x value in the interval [-1, 1], there are certain angles that are used frequently in trigonometry (0°, 30°, 45°, 60°, 90°, and their multiples and radian equivalents) …

Jul 23, 2025 · The arcsin function, also known as the inverse sine function (denoted as arcsin (x) or sin⁡−1(x), is the inverse of the sine function. It returns the angle (in radians or degrees) whose sine …

The arcsine gives us the length x of the arc on the unit circle that corresponds to this sine value. This arc is measured in radians and has the same magnitude as the angle x that generates the sine.

Use arcsin when you know the sine of an angle and want to know the actual angle. In the above figure, click on 'reset'. We know the side lengths but need to find the measure of angle C. Using a calculator …

Nov 14, 2025 · The arcsine is the inverse of the sine function. Given a number x ∈ [1, 1] (i.e., the range of values the sine function can attain), arcsin (x) is defined as the angle θ in the interval [π / 2, π / 2] …

The definition, graph and the properties of the inverse trigonometric function \ ( \arcsin (x) \) are explored using graphs, examples with detailed solutions and an interactive app. Let us examine the function \ ( …
