Introduction:
A periodic function is a function that repeats its values at regular intervals. Fourier series is a mathematical tool used to represent periodic functions as a sum of sinusoidal functions. It expresses a periodic function as an infinite sum of sine and cosine functions with different frequencies.
Given:
We are given two periodic functions, f(x) = cos²x and f(x) = sin'x, and we need to find the coefficients for their respective Fourier series.
Fourier Series:
The Fourier series representation of a periodic function f(x) is given by:
f(x) = (a₀/2) + Σ(aₙcos(nx) + bₙsin(nx))
where a₀, aₙ, and bₙ are the coefficients of the Fourier series.
Finding the Coefficients for f(x) = cos²x:
To find the coefficients for f(x) = cos²x, we need to calculate the values of a₀, aₙ, and bₙ.
Step 1: Calculate a₀:
The coefficient a₀ is given by:
a₀ = (1/π) ∫[0, 2π] f(x) dx
For f(x) = cos²x, we have:
a₀ = (1/π) ∫[0, 2π] cos²x dx
Step 2: Calculate aₙ and bₙ:
The coefficients aₙ and bₙ are given by:
aₙ = (1/π) ∫[0, 2π] f(x) cos(nx) dx
bₙ = (1/π) ∫[0, 2π] f(x) sin(nx) dx
For f(x) = cos²x, we have:
aₙ = (1/π) ∫[0, 2π] cos²x cos(nx) dx
bₙ = (1/π) ∫[0, 2π] cos²x sin(nx) dx
Finding the Coefficients for f(x) = sin'x:
To find the coefficients for f(x) = sin'x, we need to calculate the values of a₀, aₙ, and bₙ.
Step 1: Calculate a₀:
The coefficient a₀ is given by:
a₀ = (1/π) ∫[0, 2π] f(x) dx
For f(x) = sin'x, we have:
a₀ = (1/π) ∫[0, 2π] sin'x dx
Step 2: Calculate aₙ and bₙ:
The coefficients aₙ and bₙ are given by:
aₙ = (1/π) ∫[0, 2π] f(x) cos(nx) dx
bₙ = (1/π) ∫[0, 2π] f(x) sin(nx) dx
For f(x) = sin'x, we have:
aₙ = (1/π) ∫[0, 2π] sin'x cos(nx) dx
bₙ = (1/π) ∫[0,
