Update numerical_algos.py

Added my version of deriv. Its a bit simpler, however the value it returns for arctan is just a bit off.

Update numerical_algos.py
Alpha newton polynomial functions added

Added very alpha functions for constructing an interpolating polynomial using newton. Coef function runs, but does not append matrix a, so that needs to be fixed. Also Eval function is merely just a shell at the moment and hasn't really been looked at.
Added function to calculate Chebyshev nodes.

Function in alpha, doesn't work yet.
Update numerical_algos.py

just added a ton of shit

Update numerical_algos.py
Working Chebyshev Node Calculation. 

Like it says. Made a function to calculate Chebyshev nodes for a given interval and return them to a matrix x for use in interpolation.
Updated chebyshevnodes, coef, eval, 4.2.1.

Still need to finish these problems.
Updates to eval, 4.2.1. Added 4.2.2a, 4.2.2b, 4.2.10

Further improved eval to call function dependents directly. 4.2.10 has issues printing the table.
Added 4.1.1. Updated 4.2.1. Error 4.2.2a, 4.2.2b, 4.2.10

Added fully functioning versions of 4.1.1, 4.2.1. 4.2.2a, 4.2.2b, 4.2.10 all exhibit fail due to either a divided by zero error or a float is not iterable error.
Updated coef, chebyshevnodes, 4.2.1, 4.2.2a, 4.2.2b, 4.2.10. Added deriv, deriv2, 4.3.1, 4.3.2. 

All work. These problems focus on polynomial interpolation.
Minor changes.
Updated secant method & newton's method (3 versions) of root approximation.

Fixed small errors in function structure and output.
Added trapezoid_uniform function, cleaned imports.

Uploaded working function that calculates the area under a curve using n equal subintervals using the trapezoid rule. I also cleaned any imports in the data and migrated them to the top of the file, which was needed. I only just realized there is another working trapezoid function here, but there are slight differences (both functions return the exact same result).
Added additional Newton-Cotes rules, test functions (5.3.7).
Updated linear algebra functions, added Romberg algorithm (5.2.2 and 5.2.3). 

The results of this Romberg algorithm are accurate but it does not converge to the result as quickly as the one shown in our textbook.
