    Q02. Compare R = sin(2*A) and R = cos(2*A)

    Conclusion
    • The cyclic domain : A = 0 to 720 degrees
    • The petal axis directions are same
    • This patterns are defined as twins in Pattern Mathematics by Dr. Shih
    • The conditions for twins of R = sin(p*A/q) and R = cos(p*A/q) are
      • The value of p is odd
      • The value of q is even
      • The cyclic domain A = 0 to 2*q*pi
