Question Number 6644 by WAI LIN last updated on 07/Jul/16

Prove (d/dt) e_ρ =φ e_φ , (d/dt) e_φ = −φ e_ρ where dots denote differentiation with respect to time t.

$${Prove}\:\frac{{d}}{{dt}}\:{e}_{\rho} =\phi\:{e}_{\phi} \:,\:\frac{{d}}{{dt}}\:{e}_{\phi} =\:−\phi\:{e}_{\rho} \:{where}\:{dots}\:{denote}\: \\ $$$${differentiation}\:{with}\:{respect}\:{to}\:{time}\:{t}. \\ $$
