Hi,
How do you determine the domain of a trigonometric function?
For example:
y = 4cos3(x+1)-3
Thanks!
Most of them. A function such as
$\displaystyle f(x) = \cos\left(\sqrt{x}\right)$
would have a domain of $\displaystyle x \ge 0$, and a function like
$\displaystyle f(x) = \cos\left(\frac{1}{x}\right)$
would have a domain of all reals except at x = 0.
