What are Inverse Trigonometric Functions?

Inverse trigonometric functions are mathematical functions that are the inverse of the trigonometric functions: sine, cosine, tangent, cosecant, secant, and cotangent. They are used to find the angle that corresponds to a given trigonometric ratio. For example, if the sine of an angle is known, the inverse sine function can be used to find the angle itself. These functions are essential in various fields such as engineering, physics, and geometry, where angle measurements are necessary.

The principal inverse trigonometric functions are:

• Arcsine (sin⁻¹ or asin)
• Arccosine (cos⁻¹ or acos)
• Arctangent (tan⁻¹ or atan)
• Arccosecant (csc⁻¹ or acsc)
• Arcsecant (sec⁻¹ or asec)
• Arccotangent (cot⁻¹ or acot)

These functions are defined within specific domains and ranges to ensure they are valid inverses of the original trigonometric functions.
