## 1.2 Brief description 1

You can render the HTML version of this example book without changing anything:

Find the

**Build**pane in the RStudio IDE, andClick on

**Build Book**, then select your output format, or select “All formats” if you’d like to use multiple formats from the same book source files.

## 1.3 Invitation to collaborate

As you work, you may start a local server to live preview this HTML book. This preview will update as you edit the book when you save individual .Rmd files. You can start the server in a work session by using the RStudio add-in “Preview book”

Golden Rectangle

Golden rectangle derived from unit cube (b1 struts). Relative lengths of unit square diagonal (g1), unit cube diagonal (2 y1) and golden rectangle diagonal (2 r0) shown.

b0 = 1/Phi b1 = 1 b2 = Phi

g0 = g1/Phi g1 = sqrt(2) g2 = g1Phi

y0 = y1/Phi y1 = (sqrt(3))/2 y2 = y1Phi

r0 = (sqrt(1 + 1/Phi^2))/2 r1 = r0Phi r2 = r1Phi
