Question

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 1

Answer:

Step-by-step explanation:

It depends on how it is written. By definition

$\csc(x) = (\sin(x))^{-1} = \frac{1}{\sin(x)}$

$\sec(x) = (\cos(x))^{-1} = \frac{1}{\cos(x)}$

$\cot(x) = (\tan(x))^{-1} = \frac{1}{\tan(x)}$

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
