How is 3dB cutoff frequency calculated?

The cutoff frequency is defined as the frequency where the amplitude of H(jω) is 1√2 times the DC amplitude (approximately -3dB, half power point). Solve it for ωc (cutoff angular frequency), you’ll get 1RC. Divide that by 2π and you get the cutoff frequency fc.
