The function f(t) is periodic with period t = 4s. between t=0 and 4s, the function is described by: f(t) =    −1 2 1 0 < t < 1s 1 < t < 3s 3 < t < 4s (a) plot f(t) between t = −8s and t = 8s. (b) determine the exponential fourier coefficients fn of f(t) for n=0, n = ±1s, and n = ±2s. (c) using the result of part (b), determine the compact-form fourier coefficients c0, c1, c2 and c3.

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
