Vectors in NumPy

Four tasks using what you just learned. You are modeling a simple visual neuron that receives signals from retinal neurons.

Task 1: Create a firing rate vector for 3 neurons (rates: 10, 50, 2 Hz).
Task 2: Compute its length using np.linalg.norm.
Task 3: Normalize it to a unit vector.
Task 4: Compute the LGN neuron's activity using np.dot with weights [4, 3, 1].
