Let $f(t) = sin(t)$, $g(t) = cos(t)$, and $h(t) = an(t)$. Find the following. Express all answers in exact form.
$f(frac{3pi}{4}) = frac{sqrt{2}}{2}$
Based on your answer above, what point lies on the graph of $f(t) = sin(t)$?
$g(frac{pi}{2}) = 0$
Based on your answer above, what point lies on the graph of $g(t) = cos(t)$?
$h(pi) = 0$
Based on your answer above, what point lies on the graph of $h(t) = an(t)$?
