[pic] Fourier Series: Basic Results [pic] Recall that the mathematical expression [pic] is called a Fourier series. Since this expression deals with convergence‚ we start by defining a similar expression when the sum is finite. Definition. A Fourier polynomial is an expression of the form [pic] which may rewritten as [pic] The constants a0‚ ai and bi‚ [pic]‚ are called the coefficients of Fn(x). The Fourier polynomials are [pic]-periodic functions. Using the trigonometric

An example of words being used for good could be a civil rights activist trying to persuade people to get along and to treat everyone with respect

STRATEGY FOR TESTING SERIES 1. Check for known series. p-series converges if . diverges if . (Note: When ‚ the series is the harmonic series.) geometric series converges if . diverges if . telescoping series converges if a real number. diverges otherwise. 2. Use a test. NOTE: When testing a series for convergence or divergence‚ two components must be shown: (i) State the test that is used: “Therefore‚ the series [converges/diverges] by the [name of test].” (ii)
