I need help with the following problem: Consider a periodic signal !(t), with period T, such that !(t) 0, 圹 From Example 2.3.1 of the class notes, the nth Fourier coefficient of r(t) is given by in012... a) Use Fourier series, and the symmetry of the sinc function, to express r(t) in terms of cosine functions. Do we also need sine functions in this representation? b) Suppase that is a signal with Fourier transform S Find and plot the Fourier...

Show that the integral equation (t) log(1 c(s) ds COS 10 Jo has a solution in C[0, 1. Justify your answer carefully. Hint: Use the contraction mapping theorem. You may need to work with a suitable subset of ClO,1 rather than Co,. Identifying such a subset is part of the problem.

Can anyone help with this question please? Any help will be appreciated!!! Consider a general first order equation of the form where q(u) is a smooth function and assume that u(x, t) is a smooth solution. Given any smooth function u(x, t) whose support is a subset of [-R, R] × [0, T] for some R, T> 0 show that Consider a general first order equation of the form where q(u) is a smooth function and assume that u(x, t)...
