1) x(t) =\(\sum c_x(k)e ^{jkwt}\)

where as \(c_x(k) = \int_T x(t) e^{-jwt} dt \)

My question is that when which equation do we use to plot the graph.

and how do we take the values for the graph. Is it BODE PLOTS or is it simply plugging in the values.

suppose i havethis expression

\(c_x(k)= A/2 \frac {cos(k\prod-1)}{k\prod}^2\)

\(or\ i\ have\ c_x(k)= A/2 \frac {sinc(k\prod-1)}{k\prod}^2\)

then how can i graph this equation for \(c_1\ ,\ c_2\ ,\ ......\)
