Required information

Consider the following figure.

With respect to the periodic wavetorm shown in the itgure, let g$\_($n$)($t$)$ represent the Fourier series representation of f$($t$)$

truncated at nn$=1,$g$\_(1)($t$)$ has three terms, defined through a$\_(0),$a$\_(1),$ and b$\_(1).$f$(2\mathrm{.}5),$g$\_(2)(2\mathrm{.}500),$g$\_(3)(2\mathrm{.}500),$ and g$\_(5)(2\mathrm{.}500).($Round the final answer to four decimal places and include a minus sign if

necessary.$)$

The value of f$(2\mathrm{.}5)$ is

The value of g$\_(2)(2\mathrm{.}500)$ is

The value of g$\_(3)(2\mathrm{.}500)$ is

The value of g$\_(5)(2\mathrm{.}500)$ is
