Theorem
Let $\sin t$ be the sine of $t$, where $t \in \R$.
Then $\sin t$ is of exponential order $0$.
Proof 1
\(\ds \size {\sin t}\) | \(\le\) | \(\ds 1\) | Real Sine Function is Bounded | |||||||||||
\(\ds \leadsto \ \ \) | \(\ds \size {\sin t}\) | \(<\) | \(\ds 2\) | |||||||||||
\(\ds \) | \(=\) | \(\ds 2 e^{0 t}\) | Exponential of Zero |
$\blacksquare$
Proof 2
The result follows from Real Sine Function is Bounded and Bounded Function is of Exponential Order Zero.
$\blacksquare$
