Define periodic function, even function, and Fourier series.

Here are the solutions to the questions: 1a) Define the following: i) Periodic function: A function f(x) is periodic if there exists a positive constant T such that f(x+T) = f(x) for all x in the domain of f. The smallest such positive T is called the period. ii) Even function: A function f(x) is an even function if f(−x) = f(x) for all x in its domain. Even functions are symmetric about the y-axis. iii) Fourier series: A Fourier series is an expansion of a periodic function into a sum of sines and cosines. It represents a

Here are the solutions to the questions:

1a) Define the following:

i) Periodic function: A function $f(x)$ is periodic if there exists a positive constant $T$ such that $f(x+T) = f(x)$ for all $x$ in the domain of $f$ . The smallest such positive $T$ is called the period.
ii) Even function: A function $f(x)$ is an even function if $f(-x) = f(x)$ for all $x$ in its domain. Even functions are symmetric about the y-axis.
iii) Fourier series: A Fourier series is an expansion of a periodic function into a sum of sines and cosines. It represents a
