     - $g(x) = x(x-2\pi)$ (Hint: Use integration by parts)
 
 2. Show that  
-$ \int_0^{2\pi} sin^4(x) dx = \frac{3 \pi}{4} $  
+$\int_0^{2\pi} sin^4(x) dx = \frac{3 \pi}{4} $  
 (Hint: write out the exponential fourier expansion of $sin^4(x)$.)
 
 3. Compute the exponential Fourier coefficients of $sin^2(x)$:  
-$ a_n = \frac{1}{\sqrt(2\pi)} \int_0^{2\pi} sin^2(x) e^{-inx} dx $  
+$a_n = \frac{1}{\sqrt(2\pi)} \int_0^{2\pi} sin^2(x) e^{-inx} dx $  
 and use this to show that  
-$ \int_0^{2\pi} |sin^2(x)|^2 dx = \sum |a_n|^2 $  
+$\int_0^{2\pi} |sin^2(x)|^2 dx = \sum |a_n|^2 $
