On second thought I suspect you have that much down and you fail to see how to
branch of into the right direction at 1/n of the length and to the left at 1/k
for k < n with different angles.

Here is a hint I posted some N years ago for my freshmen: Recall the hint: "Think of the problem as drawing a straight line, givenits starting point and an angle in, say, radians." Graphically the situationlooks like this:Your given the starting point (x0,y0) the _length_ and the angle _a_ and you
I suppose I should have clarified that, yes, its from the book, section 27.1.4.

I have a nearly working code, it draws the tree, but it is slightly off. I
realize what is wrong that is causing the problem, for each recursive call I
used a set angle. The tree draws all the left branches at the same angle and
all right branches at the same angle. I end up with a picture of a
