Explore Euler’s formula — the elegant link between the constant e, the imaginary unit i, and the trigonometric functions cosine and sine. This video introduces the concept of complex exponentials, explains how e^{ix} traces a unit‑circle rotation, and breaks down the relationship e^{ix}=cos x + i·sin x. You’ll see worked examples, including the classic result e^{iπ}=‑1, and a practice problem for e^{iπ/2}. The lesson concludes with key takeaways and real‑world applications, highlighting how the formula underpins analysis of alternating currents in electrical engineering and wave behavior in signal processing.
