Nature of $y=\cos(e^{-x})$

Can anyone explain me the nature of the graph of $y=\cos(e^{-x})$ ?

You can tell me why this graph behaves in such a way, how to calculate it's period, why the period is becoming infinite when $x$ approaches $-\infty$ , etc.

In other words, tell me everything you can know about the properties of the graph.

It's obvious that there's no period.

Okay, there's no period, but can you tell me why is the graph becoming compact, when $x$ becomes more negative?

Vilakshan Gupta - 2 years ago

@Vilakshan Gupta – I want that, if we are not given the graph , how and what conditions we need to find to draw the graph by hand?

@Vilakshan Gupta – Hint: See this relevant answer.
