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 …

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 …

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 …

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.).

Jul 23, 2025 · Arcsine function, commonly written as arcsin (x) or sometimes as sin⁻¹ (x), is the inverse of the sine function. It allows us to determine the angle whose sine is a given value.

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 …

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. …

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 …

Arcsine formulas. The identities for sine, cosine, tangent and cotangent of arcsine. Sum of arcsine and arccosine...
