Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Just like when you did R = np.array([0, 0]) There's an R = command that will let you add up your vectors to give you that resultant vector.

what is "the resultant" of vectors? the sum?

when you add two arrays of the same shape with +, you get a new array of the same shape that is the element-wise sum

!e

import numpy as np
arr1 = np.array([1, 2, 3])
arr2 = np.array([4, 5, 6])
print(arr1 + arr2)
print(arr1.sum())
print(np.sum(arr1 + arr2))

:white_check_mark: Your 3.12 eval job has completed with return code 0.

001 | [5 7 9]
002 | 6
003 | 21

@glad heath make sense?

that doesn't have any effect.

He could just do R = F1_vec + F2_vec + F3_vec

[valid hearth]

what was the solution?
