Sine Wave with 180° Phase Shift (Inverted)
A 180° phase shift fully inverts the sine wave, making it equivalent to -sin(x).

Shift a sine wave by 180 degrees to invert it, which is equivalent to multiplying the amplitude by -1.
Frequently asked questions
- What is the RMS value used for?
- Root-mean-square (RMS) voltage or current tells you the effective power of an AC signal. Mains electricity (e.g. 120 V / 230 V) is quoted in RMS.
- What is angular frequency?
- Angular frequency ω = 2πf, measured in radians per second. It's often more convenient in equations than ordinary frequency f.
