Basic Mathematics for Robotics, Chapter 3, Exercise 3.1


Please see the function given in ex. 3.1

then see the code (part of it describe the function)

(marked in yellow mean 0.25x^2)

according to the following derivative


the code should be

# function f(x)
f = 0.5*x**2+3


f = (x**2)/2+3

and not

f = (x/2)**2+3 which will result in df=0.5*x+3

Is my small penny analysis here is correct?
If so, please correct the notebook.
If not, sorry for the trouble.

Thank you

Hello @TAURD ,

You are totally right, I’ve already fixed this in the notebook. Many thanks for the feedback!
