Euler's Formula as a Rotation Matrix

In this video I rewrite Euler's Formula to make it in the form of a rotation matrix. This follows from my earlier videos on equating complex numbers as vector rotations. Furthermore, for the case x = π, we get Euler's Identity, which in matrix form is just the negative Identity Matrix. Thus, even Euler's famous formula can be interpreted as simply rotating a vector. Since complex numbers are used in many areas of physics, such as electromagnetism and quantum mechanics, it may be fruitful to start reinterpreting other famous formulas as rotational matrices! In fact, this is exactly what Fractal Woman has attempted to do already: https://www.youtube.com/user/FractalWoman/search?query=complex%20numbers
