Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle -{{9}\over{x-4}} &\text{if }\displaystyle x\lt1\\ \\ \displaystyle 3 x +5 &\text{if }\displaystyle 1\le x\lt3\\\\\displaystyle \sqrt{8 x -8} &\text{if } \displaystyle x\ge3 \end{cases} \]
Evaluate \(f(3)\).
Evaluate \(f(3)\).
