I think I realize my mistake. When defined in terms of the triangular function, the given function is indeed ##y(t)=2tri(\frac{t}{2})-tri(t)##.
FT of ##\mathrm{tri}(t)##: ##\mathrm{sinc}^2(f)##
FT of ##\mathrm{tri}(\frac{t}{2})##: ##\mathrm{sinc}^2(2f)##
Therefore FT of y(t)...
Well, ##y(t)=2\mathrm{tri}(\frac{t}{2})-\mathrm{tri}(t)## is equivalent to a constant +1. So, that matches the given function over the region ##-1\leq t\leq 1## only.
To be honest, I'm stuck. I have not found a transform that agrees with the given function.
Is the following correct for...
The book I am using is "Introduction to Analog & Digital Communications" by Simon Haykin & Michael Moher, 2nd ed. They define the Fourier transform of a triangular pulse as ##AT^2\mathrm{sinc}^2(fT)##. That is all I could find in the book. However, I found the following definition of the unit...

I guess what I am getting at is, does there exist a set of equations that works for every periodic function to find the Fourier coefficients? Or, do you have to modify your approach every time?
I hadn't been receiving much positive feedback, so I just wanted to take a step back first.
So...
Fine. Based on the reply's to this thread thus far, I know next to nothing about how to solve this problem. I accept this.
So, if you are willing, I would like to solve this problem together step by step.
Based on what I read at this link: Any periodic function may be expressed as an infinite...
Complex coefficients c_n (exponential form?)
c_0 will remain the same value of 1/2
c_n=\frac{1}{T_0}\int ^{\frac{T_0}{2}}_{\frac{-T_0}{2}}x(t)\mathrm{exp}(-j\omega nt)dt
=\frac{1}{T_0}(1+\int ^{t_0}_{-t_0}e^{-j\omega nt}dt)

I probably knew the difference at some point in the past, but I could use a refresher.
I believe the answers i have calculated are in the trig form. To get the exponential form, I'm thinking I will need to use Euler's formula. Is this correct?
