5 Questions
Why are trigonometric functions well understood and useful in analyzing functions?
Because expressing a function as a sum of sines and cosines makes many problems easier to analyze
What is a Fourier series?
An expansion of a periodic function into a sum of trigonometric functions
Can Fourier series be used to approximate arbitrary functions?
No, because most functions have infinitely many terms in their Fourier series, and the series do not always converge
What do Fourier series focus on in terms of convergence study?
The behaviors of the partial sums as more and more terms from the series are summed
What determines the coefficients of the Fourier series?
Integrals of the function multiplied by trigonometric functions
