The values of a periodic function $f(t)$ in one full period are given; at each discontinuity the value of $f(t)$ is that given by the average value condition $f(t) = \frac{f(t^+) + f(t^-)}{2}$. Sketch the graph of $f$ and find its Fourier series. f(t) = \begin{cases} 0 & -1 < t < 0 \\ 19 \sin(\pi t) & 0 < t < 1 \end{cases} Sketch the graph of $f$. Choose the correct graph below. Find the Fourier series of $f$. f(t) = (Type a series using $n$ as the index variable and 2 as the starting index. Type an exact answer, using $\pi$ as needed. Use parentheses to denote the summand. Use parentheses to clearly denote the argument of each function.)

18. On February 24th 1987, a supernova was seen in the constellation of Dorado, in the vicinity of the Tarantula nebula in the Large Magellanic Cloud. Neutrinos from Supernova 1987A reached Earth travelling a distance of 55 kpc. (a) The neutrino flux from SN 1987A was estimated to be $1.3 \times 10^{10}$ cm$^{-2}$ at the location of Earth. If the average energy per neutrino was approximately 4.2 MeV, estimate the amount of energy released via neutrinos during the supernova explosion. (b) The neutrinos were found to have energies in the range 6-39 MeV. If the spread of 12s in arrival times was caused by neutrinos of different energies traveling at different speeds, show that the neutrino mass cannot be much more than about 20 eV.
