I have touched the Idea-section, trying to beautify a little. In particular I added a little diagram, illustrating what the text is saying:

$\array{ & && \mathbb{R} \\ & & {}^{\mathllap{cos}}\nearrow & \big\uparrow{}^{ \mathrlap{pr_1} } \\ \mathbb{R} \overset{exp}{\longrightarrow} & S^1 &\hookrightarrow& \mathbb{R}^2 &\simeq& \mathbb{R} \times \mathbb{R} \\ & & {}_{\mathllap{sin}}\searrow & \big\downarrow{}^{ \mathrlap{pr_2} } \\ & && \mathbb{R} } \,,$

Eventually parts of this page should really be at cos and sin.
