Course 5, Week 4, Assignment 1, Exercise 2

I have a question on this exercise, for anyone who can offer help. I’m confused when applying sin and cos to angle_rads. The exercise has prewritten:
angle_rads[:, 0::2] = None
But in the previous line, angle_rads = get_angles(,) so I believe it’s a 1D vector.

Edit: In fact, I figured out that position should be made into a column vector, so that angle_rads becomes an array. This resolved the issue I was having…

Great that you solved it!
