## Fourier Series

A Fourier series is a way of representing a periodic function as a sum of sine and cosine functions with different frequencies and amplitudes. The Fourier series can be used to analyze the properties of periodic signals, such as sound waves, light waves, and electrical currents . The Fourier series can also be used to solve some types of partial differential equations, such as the heat equation and the wave equation .

One of the main concepts in Fourier series is the Fourier coefficient, which is the amplitude of each sine or cosine term in the series. The Fourier coefficient can be calculated by using the following formula:

where is the periodic function with period , and is a positive integer. The Fourier series of can then be written as:

where is the average value of over one period.

Here is an example of a question and answer for Fourier series:

Question: Find the Fourier series of the function on the interval .

Answer: First, we need to extend the function to a periodic function with period . We can do this by defining for any integer . This means that the function is symmetric about the origin and has a discontinuity at every multiple of . Next, we need to calculate the Fourier coefficients using the formulas above. We have:

0" title="\large a_n=\frac1\pi\int_-\pi^\pix^2\cos(nx)dx=0,\quad \textfor \quad n>0" />

0" title="\large b_n=\frac1\pi\int_-\pi^\pix^2\sin(nx)dx=-4(-1)^n,\quad \textfor \quad n>0" />

The last two integrals can be found by using integration by parts twice. Therefore, the Fourier series of on the interval is:

## Laplace Transforms

A Laplace transform is a technique that converts a function of time into a function of a complex variable, called the Laplace variable. The Laplace transform can be used to simplify the analysis and solution of differential equations, especially those involving initial value problems. The Laplace transform can also be used to study the stability and frequency response of systems, such as electrical circuits, mechanical systems, and control systems.

One of the main concepts in Laplace transforms is the Laplace transform pair, which is a pair of functions that are related by the Laplace transform. The Laplace transform pair can be written as:

where is the function of time, is the function of the Laplace variable , and is a real constant that satisfies the condition of convergence of the integrals. The symbol denotes the Laplace transform operator, and the symbol denotes the inverse Laplace transform operator.

Here is an example of a question and answer for Laplace transforms:

Question: Find the inverse Laplace transform of .

Answer: To find the inverse Laplace transform of , we need to use the following formula:

This formula can be derived by using the method of partial fractions and the residue theorem. By comparing the formula with , we can see that . Therefore, we have:

0" title="\large \fracd^2Xdx^2,\quad 00" />

This equation implies that both sides must be equal to a constant, which we denote by . Therefore, we have two ordinary differential equations:

0" title="\large \fracdTdt+\lambda T=0,\quad t>0" />

The first equation has the general solution:

where is an arbitrary constant. The second equation has different solutions depending on the value of . We consider three cases:

Case 1: If , then the equation becomes:

The general solution is:

where and are arbitrary constants. Applying the boundary conditions, we get:

This implies that , and hence . This solution is trivial and does not contribute to the solution of the PDE.

Case 2: If , then the equation becomes:

The general solution is:

where and are arbitrary constants. Applying the boundary conditions, we get:
