Web the second solution method makes use of the relation \(e^{it} = \cos t + i \sin t\) to convert the sine inhomogeneous term to an exponential function. Web $$e^{ix} = \cos x + i \sin x$$ fwiw, that formula is valid for complex $x$ as well as real $x$. Here φ is the angle that a line connecting the origin with a point on the unit circle makes with the positive real axis, measured counterclockwise and in radians. Y = acos(kx) + bsin(kx). Web euler’s formula for complex exponentials according to euler, we should regard the complex exponential eit as related to the trigonometric functions cos(t) and. This formula can be interpreted as saying that the function e is a unit complex number, i.e., it traces out the unit circle in the complex plane as φ ranges through the real numbers. The trigonometric spectrum of cos ( k ω t) is single amplitude of the cosine function at a.
