It also makes doing many common operations on complex number a lot easier. The exponential function $f(z) = \exp(z) = e^z$ is defined as: -$$\exp(z) = e^{x + {\rm i}y} = e^{x} + e^{{\rm i} y} = e^{x} \left( \cos y + {\rm i} \sin y\right).$$ +$$\exp(z) = e^{x + {\rm i}y} = e^{x} e^{{\rm i} y} = e^{x} \left( \cos y + {\rm i} \sin y\right).$$ The last expression is called the *Euler identity*. **Exercise** Check that this function obeys -- GitLab
