We can express the trigonometric functions in terms of the complex exponentials eiz; e?iz since we know that cos(z) is even in z and sin(z) is odd in z.

Fuhr, Lehrstuhl A fur Mathematik, RWTH Aachen, WS 07 geometric setting, the unit circle is a natural protractor that measures angles on the x-y plane, and sine and cosine are functions that resolve angles into vertical and horizontal components. In more advanced courses, analytic reasoning is used to extend these functions to the complex domain: cos(? + ?i) = cos? cosh? ? i sin then it follows from the definition of the complex exponential that cosz and sinz are the standard trigonometric functions when z = x. Moreover, since the exponential now is known to be differentiable it follows from the chain rule that cosz and sinz are differentiable. Moreover, d dz cosz = ieiz ? e?iz. 2. = ?sinz and similarly,.

Recall that exp : C > C? is surjective (onto), that is, given w ? C? with w = ?(cos? + isin?), ? = |w|, ? = Arg w we have ez = w where z = ln? + i?

In these notes, we examine the inverse trigonometric and hyperbolic func- tions, where the arguments of these The complex sine and cosine functions are seen to be sinz = sinx coshy + icosxsinhy, cosz = cosxcoshy ? isinx sinhy.
