Hi,

Here is my question: How do I calculate the t-values for the four points (x,y) where the curve below intersects itself with an accuracy of 1x10^-7

x==(Cos[6 t])^2

y==2Sin[7 t]

in the intervall: [0,2Pi/7]

Thank you in advance

(Plot the parametric curve and you will understand what I am asking for)
