Program in Numpy (Python) that takes in five points from a graph and returns the coefficients for the function of that graph

I want to create a program in Numpy (Python) that takes in five points from a graph and returns the coefficients for the function of that graph. Mathematically it would be like this:

PS: I know this question is a lot so even if you can't completely answer it I understand but I would appreciate a tip or at least the name of a NumPy library that could help me do this and I'll research it.

enter image description here

From that, I just want to know how to implement it into NumPy. Please help!

I know I have to subtract the polynomials so I have this:

def find_conic():
  # define the polynomials
  # p(x) = 5(x**2) + (-2)x +5
  px = (5,-2,5)
  
  # q(x) = 2(x**2) + (-5)x +2
  qx = (2,-5,2)
  
  # subtract the polynomials
  rx = np.polynomial.polynomial.polysub(px,qx)
  
  # print the resultant polynomial
  print(rx)

find_conic()

I would then have to substitute the subtracted equation into each other to get the equation for a for example.

How to split a rinex file if I need 24 hours data

Trying to divide rinex file using the command gfzrnx but getting this error. While doing that getting this error msg 'gfzrnx' is not recognized as an internal or external command Trying to split rinex file using the command gfzrnx. also install'gfzrnx'. my doubt is I need to run this program in 'gfzrnx' or in 'cmdprompt'. I am expecting a rinex file with 24 hrs or 1 day data.I Have 48 hrs data in RINEX format. Please help me to solve this issue. source https://stackoverflow.com/questions/75385367/how-to-split-a-rinex-file-if-i-need-24-hours-data

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
