Learn Physics or Get Bored Trying

My brain hurts.

Currently reading some results regarding complex numbers, the proof of which involves a radius term R, euler’s notation Re^{i\theta}, and the splitting of a complex number z=\mathop{\mathrm{Re}} z + i\mathop{\mathrm{Im}} z. So finding terms like \mathrm{Re}^{i\theta} and even \mathop{R\mathrm{e}} z is doing my nut. This is in a printed book too, so it’s not a bad e-book translation error.

On the other hand, posting this did teach me how to define roman-style functions in \LaTeX without \operatorname (which WordPress doesn’t support on their hosted blogs). If anyone cares, it’s \mathop{\mathrm{Op}}.
