L{cos}(s) = $\int_{0}^{\infty} e^{-st} \cos(at) dt$ $u = \cos(at)$ $dv = e^{-st}dt$ $du = -a\sin(at)dt$ $v = -(1/s)e^{-st}$ $= -(1/s)e^{-st}\cos(at) \Big|_{0}^{\infty} - \int_{0}^{\infty} (a/s)e^{-st}\sin(at)dt$ $u = \sin(at)$ $dv = (a/s)e^{-st}dt$ $du = a\cos(at)dt$ $v = -(a/s^2)e^{-st}$ $= (1/s) - [-(a/s^2)e^{-st}\sin(at) \Big|_{0}^{\infty} - \int_{0}^{\infty} -(a/s^2)e^{-st}a\cos(at)dt]$ $= (1/s) - \frac{a^2}{s^2} \int_{0}^{\infty} \cos(at)e^{-st}dt$ Notice that this last integral is the same as the integral we started with. Treat this like an equation and move the integral to the left hand side: $(s^2+a^2) \int e^{-st} \cos(at) dt = \frac{1}{s}$ Therefore $\int e^{-st} \cos(at) dt = \frac{s}{s^2+a^2}$
