starting point is diff equation
We use Euler discretization to turn this into a discretized problem
The linear/quadric problem is a nimportant example
with cost function
We want to estimate A and B and d
If noise terms are all 0’s the correct A and B has been found
As long there is a triplets of x’s u’s and next x’s it doesn’t matter where they are.
Make one big dataset simpliies the problem
