   Format: MarkdownItexI 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]]_. <a href="https://ncatlab.org/nlab/revision/diff/trigonometric+function/7">diff</a>, <a href="https://ncatlab.org/nlab/revision/trigonometric+function/7">v7</a>, <a href="https://ncatlab.org/nlab/show/trigonometric+function">current</a>

   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.
