let us take formula_59 and formula_63 as the unit circle ``u.’’ and formula_64 as the cosine curve









































note that formula_66









































for the transformed curve for formula_67, see the figure.









































the transformed curve formula_68 has the parametric equations









































section::::"n"-curves and their products.:example 2.









































denote the curve called crooked egg by formula_69 whose polar equation is









































its parametric equations are









































let us take formula_73 and formula_74









































where formula_75 is the unit circle.









































the "n"-curved archimedean spiral has the parametric equations









































see the figures, the crooked egg and the transformed spiral for formula_78.
