Is this right? and how do I draw the Fourier transform graph
\begin{align*} F(\omega) & = \int_{0}^{t_0}P_{ro}\Bigl(1-\frac{t}{t_0}\Bigr)\exp{(-jwt)}\,dt\\ & = P_{ro}\Bigl(1-\frac{t}{t_0}\Bigr)\frac{\exp{(-jwt)}}{-jw} +\int_{0}^{t_0}\frac{\exp{(-jwt)}}{-jw}\frac{P_{ro}}{t_0}\,dt\\ F(\omega) & = P_{ro}\Bigl(1-\frac{t}{t_0}\Bigr)\frac{\exp{(-jwt)}}{-jw} +\frac{P_{ro}}{t_0}\frac{\exp{(-jwt)}}{(-jw)^2} \end{align*} Applying the limits $0$ $<$ t $<$ $t_o$
\begin{align*} F(\omega) & = P_{ro}(1 + \frac{\exp{(-jwt)}}{(-jw)^2} -\frac{1}{t_0}) \end{align*}
