... The sinusoidal voltage and current in an inductor are out of phase by 90o The voltage lead the current by 90o or the current lagging the voltage by 90o You can express the voltage leading the current by T/4 or 1/4f seconds were T is the period and f is the frequency ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
