I need help with Fourier transform

[marcelinejinx]

Well, i have this function f(t)=2+cos(2*pi*fc*t) and i have to obtain the fourier transform of f(t), do u know how this number 2 adding can be treated in the transform?

depending on which definition of the Fourier Transform you use

\(\displaystyle \mathscr{F}\{c\} =2\pi c \delta(\omega),~c \in \mathbb{R}\)

\(\displaystyle \delta(\omega)\) is the Dirac delta function in the frequency domain.
