I am new to Python learnig for a class. When I try using trajectory I receive
an error. Here is the code:
def logistic(x):
return 4*x*(1-x)
ds_logistic11=trajectory(logistic,0.11)
SyntaxError: invalid syntax
Hi Carla,
Be sure to copy and paste in exactly the code that results in the error.
As you can see below when I use your example there is no error. This
makes it hard as we now have to guess what you may have done.
I do see one issue -- when you intend to execute your function you need
to enclose the parameters in parens. eg, use logistic(0.11)
