Fourier series: Coefficients of Fourier series
Piecewise continuous and smooth functions
Consider the piecewise defined real function \[f(x)=\begin{cases}\displaystyle -{{1}\over{5 x -9}}-3 &\text{if }\displaystyle x\le1\\ \\ \displaystyle -5 x ^2-8 x -10 &\text{if }\displaystyle 1\lt x\le7\\\\\displaystyle 10-6 x &\text{if } \displaystyle x\gt7 \end{cases} \]
Evaluate \(f(6)\).
Evaluate \(f(6)\).
