To determine the inverse of a reciprocal function, such as Cot - 1 (2) or Sec -1 (-1), you have to change the problem back to the function's reciprocal one of the three basic functions and then use the appropriate inverse button. There can be different senses. The difference between "inverse" and "reciprocal" is just that. Fundamentally, they are the trig reciprocal identities of following trigonometric functions Sin Cos Tan These trig identities are utilized in circumstances when the area of the domain area should be limited. Inverse Trig Functions. Notation: The inverse function of sine is sin -1 (x)=arcsin (x), read as "the arcsine of x." As a function, we can say that y=arcsin (x). It also termed as arcus functions, anti trigonometric functions or cyclometric functions. The inverse of g is denoted by 'g -1'. The oldest trig tables were for chords, and you can easily find tables from the 19th century with haversines, exsecants, and others. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry .
