If I tell you: “A cosine signal has amplitude 1 Volt, and

Frequency 50Hz” then you can draw the signal in time domain
Is there any other representation of this Cosine signal?

What we have seen so far is sine and cosine which are

“periodic signals”
What if the signal non-periodic? How to obtain Fourier Transform
