Basic Mathematics for Robotics, Chapter 3, Exercise 3.1

[TAURD]

Hello

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

or

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!
