  1. Golden Ratio 王柏雄B9202003 何宗祐B9202010 吳士皓B9202015 俞錫全B9202036

  2. Phi • The golden number 1.618…… • One way to find Phi is to consider the solutions to the equation • x = (1+√5)/2 ~ 1.618... or x=(1-√5)/2 ~ -.618... • and 1.618……is the golden number

  3. We consider the first root to be Phi. We can also express Phi by the following two series Phi =                                                       or Phi =

  4. Golden Rectangle • When we draw a rectangle that has sides A and B that are in proportion to the Golden Ratio Golden rectangle. • Golden Rectangle most pleasing rectangle to the eye.

  5. Assume that rectangle ABCD is a Golden Rectangle. Hence, AD/AB =AE/ED • But, FE = AE, and so FE/ED= Phi • Hence, rectangle FCDE is a Golden Rectangle

  6. If we connect the vertices of the regular pentagon, we can get two different Golden Triangles. • The blue and red one are all golden triangle.

  7. If we take the isosceles triangle that has the two base angles of 72 degrees and we bisect one of the base angles, we should see that we get another Golden triangle that is similar to the first (Figure 1). • we can get a set of Whirling Triangles (Figure 2).

  8. Golden Ratio and Investment 0.191,0.382,0.5,0.618,0.809 Elliot’s Waves theory

  9. Above data can just be used for reference, the risk you have to take on your own if you invest in this way.

  10. The Use of Golden Section Number in War • Strong and mysterious • By chance or bound to ? • Coincidence or regular pattern?

  11. The battle line The compose of an army Time Rate of destruction

  12. AMAZING • If we draw a line from the center A to the edge E, it will intersect with B, C, D • Then we can find that • And it fit golden ratio!!!

  13. The ratio of the maple leaf’s width to it’s vein • The ratio of upper wings’ length to the lower one • They are all fit golden ratio

  14. Are u a model? • Length from head to belly button = x • Length from belly button to the ground = y • If y/x = 1.618…… • Congratulation!!! You can be a model.

  15. Thank you for your kind attention!
