A very important value in mathematics is called the Golden Ratio. It appears in art and nature as well as architecture. This is because many believe this ratio creates the most beautiful proportions.
- The Golden Ratio is expressed as $\frac{a}{b}=\frac{a+b}{a}$. The Greek letter $phi$, denoted as $\varphi$. Show all your work and explain your steps. Note, this should be your own work and internet resources should not be used.
- You learned about the imaginary unit $i$ in this chapter. We defined $i=\sqrt{-1}$ and used the fact that $i^2=-1$. Now explore other powers of $i$. Determine a rule for $i^n$ is any integer. Provide examples to show your rule is valid.
