Question

is sin^-1 the same as cosecant?

Answer 1

normally
\[ \sin^{-1} (x) \]
means the inverse sine

as opposed to the sin to the negative 1 power

but if you do mean 1/sin(x) then yes this is the cosecant

Answer 2

I thought sin^-1 WAS the inverse of sine???
But is cosecant and the inverse of sine the same thing?
Like, if a question asked me what the cosecant of a number was, all I would have to do is hit the inverse of sine button on my calculator???

Answer 3

As @phi wrote above, in this case, do not interpret the "exponent" -1 as being a normal exponent of -1. In this case, the symbol "-1" that looks like an exponent means the inverse function.
