What is the difference between a natural domain and a regular domain?

anonymous · Answer

am i asking this in the wrong spot?

anonymous · Answer

no just post a question.  like 
find 
$$\cos(\sin^{-1}(x))$$ or 
is 
$$f(x)=\frac{x}{x^2-1}$$ even odd or neither

anonymous · Answer

okay, so using the question you just posted as an example.. how would i figure out whether its even or odd or neither

zarkon · Answer

evaluate f(-x)

anonymous · Answer

Sorry to sound like an idiot but to evaluate simplify the denominator?

anonymous · Answer

in the function replace all the x with -x if it comes out to be -x then it is an odd function

anonymous · Answer

oh, okay. thanks.
