Python: numpy arrays vs. lists

In a previous video (here    • Python stuff about lists you need for physics  ) I used Web VPython to do some lists stuff. Just for completeness, here's the same stuff using numpy arrays If you want to do some awesome stuff with python for your physics course, you might need a solid understanding of lists. Here's the test: 1. Make a list of x values from 0 to 2 with spacing 0.2. 2. Make a list of function values for those same x’s such that f(x) = A*sin(k*x). Pick k such that f(0) = f(2) = 0. Let A = 1. 3. Plot f(x) vs. x. Yes, the function from question 2. 4. Make a new list and call it f2(x). Set the values equal to f(x). 5. Find the integral of f(x)dx from 0 to 2. Set this equal to I 6. Change f2(x) so that it’s integral f2(x)dx is equal to 1. 7. Make a new function f3(x) = x^2-bx. Create an animated graph as b goes from 0 to 4 using a increment in b of 0.1 here is the code https://trinket.io/glowscript/5260426134
