Hello, can you help me understand this problem and how to work it out.

7.4 Use the orthonormal waveforms in Problem P-7.3 to approximate the function x(t) : sin(tt/4) 4 1 2 1 21 3 Figure P-7.3 over the interval 0<t <4 by the linear.combination 3 Î(t) = n=1 1. Determine the expansion coefficients {cn} that minimize the mean-square approximation eror p4 [x(t) - (t)]² dt or E = 2. Determine the residual mean square error Emin.
