Modeling using Second and Third Order Polynomials

One of the advantages of rational functions is that even rational functions with low-order polynomials can provide excellent fits to complex experimental data. Linear-to-linear rational functions have been used to describe earthquake plates. As another example, a linear-quadratic fit has been used to describe lung function after

Primes and Odd Numbers

Prove that if every even natural number greater than 2 is the sum of two primes, then every odd natural number greater than 5 is the sum of three primes. Please see the attached file for the fully formatted problems.

Simplifying Radicals

It is important to simplify radical expressions before adding or subtracting to get terms with like radicals. Once we find terms with like radicals we can then add or subtract the expressions. Simplifying the expression and obtaining terms with like radicals makes the problem less complex when solving. We can follow the same rul
