Integral of [h(t-pi/4) - h(t)] cos(2t) e^-st dt
limits of integration 0 to infinity
s > 0
need assistance.
regards
h(t) is what function, the unit step?Integral of [h(t-pi/4) - h(t)] cos(2t) e^-st dt
limits of integration 0 to infinity
s > 0
$\displaystyle
\int_{t=0}^{\infty} u(t-k) \cos(2t) e^{-st} \ dt=\text{Re}\left[\int_{t=k}^{\infty} e^{(-s+2\text{i})t}~dt\right]
$
