Figure 31 : Patterns of R=1+sin(p*A/4) and R=1+cos(p*A/4)
Product no. Program Pattern
Q1. What is the diagram ?
-
* Compare r=1+1*sin(p*A/4) and r=1+1*cos(p*A/4)
* Patterns are congruent
* The direction are same if p is odd and q = 4
Q2. Can we get a rule from the patterns ?
A2. Yes
- If p=odd, q=4 and M=odd
- The sine and cosine patterns are congruent with same direction
- In Pictorial Mathematics, it is defined as Twin patterns
