Trigonometric functions like sin, cos, and tan are many-one in their natural domains, which means their inverses do not exist unless the domain is restricted. Once we restrict each function to a carefully chosen principal value branch, the inverse becomes well-defined. For example: - sin x is restricted to [/2, /2] its inverse is sin⁻ x - cos x is restricted to [0, ] its inver...
