Are the terms CSC, SEC, and COT equivalent to the terms Sin^-1, Cos^-1, and Tan^-1? Are the three pairs of terms the same thing just written differently, or are they entirely different?

Answer:

Explanation:

It depends on how it is written. By definition


\csc(x) = (\sin(x))^(-1) = (1)/(\sin(x))


\sec(x) = (\cos(x))^(-1) = (1)/(\cos(x))


\cot(x) = (\tan(x))^(-1) = (1)/(\tan(x))

however the functions


\sin^(-1)(x), \cos^(-1)(x), \tan^(-1)(x) are the inverse functions of sine, cosine and tangent respectively. So, they are not equivalent functions
