# You can make a sunflower pattern in Exc

You can make a sunflower pattern in Excel or Libre Office Calc by using these two cell formulae in A1 and B1:

= SQRT(ROW(A1)) * COS(ROW(A1)*2.4)

= SQRT(ROW(B1)) * SIN(ROW(B1)*2.4)

and then extending the formulae down over a few hundred cells and making a scatter graph.

= SQRT(ROW(A1)) * COS(ROW(A1)*2.4)

= SQRT(ROW(B1)) * SIN(ROW(B1)*2.4)

and then extending the formulae down over a few hundred cells and making a scatter graph.
