I have a signal like \$\sin(2t)\$.
The frequency of this signal is \$f=\frac{1}{\pi}\$, but I am confused here because this \$\pi\$ equals 3.14 or 180 degrees if the signal is \$\sin(2\pi t)\$, then \$f=1\$ and everything is clear.
Please tell me what is the difference between them?

Yes, whoever is setting the question is making the maths easy. One cycle per second or 1 Hz.
