sically, Tree 1 is just a vertical line, Tree 2 is that line plus two branches, Tree 3 is Tree 2 but with two additional branches on each of the original ones, and so on. Please help! I don't understand how recursions are supposed to be used with this and how to call a previous tree function. Below are additional instructions my teacher gave me.
draw-tree3 [ levels blen bangle]
levels : number of levels
blen : length of each branch
bangle : angle of the branches
The branch length should decrease as the function calls itself. This does NOT mean you decrease a variable, it means that just like fib(n-1) or fib(n-2) you decrease the parameter as you pass it to the next copy.
----Your slider is the STARTING value, the parameter can be changed every time your function is called.
Have the branch decay by multiplying by 0.85 before passing it to the next recursive call.
-When this works, try making the branch decay a slider from 0.1 to 0.9 in increments of 0.01
