Low Speed Doppler Shiftcan be expanded by the binomial expansion and only the first two terms of the expansion used
When expressed in terms of the frequency shift, this becomes

Doppler Expression ExpansionTo get a simplified expression for the Doppler frequency expression, the square root in the expression can be expanded using the binomial expansion as For low speeds where v << c, the first two terms give a good approximation of the Doppler shift:
