Using Euler's Formulas to Obtain Trigonometric Identities Written by tutor Jeffery D. In this lesson we will explore the derivation of several trigonometric identities, namely cos (x + y) = cos x cos y - sin x sin y and sin (x + y) = sin x cos y + sin x cos y also cos 2x = cos2 x - sin2 x along with sin 2x = 2 sin x cos x and lastly, DeMoivre's... read more
