Problem :
What is arccos()?
+2nΠ, +2nΠ, where
n is an integer.
Problem :
What is arcsin(0)
nΠ, where
n is an integer.
Problem :
What is arccos()?
There is no solution, because there exists no angle whose cosine
> 1.
Problem :
Why aren't the inverse relations functions?
The inverse relations aren't functions because they don't assign a specific
output to each input.
Problem :
What are the domains of arcsine, arccosine, and arctangent?
The domains of arcsine and arccosine are
[- 1, 1]. The domain of arctangent is
all real numbers. Note: Although they aren't functions, the term domain can be
used to describe the possible inputs of the relations.
