## Laplace Transform of cos^4t | Find L{cos^4t}

The Laplace transform of cos^4t is equal to 3/(8s) + s/[2(s2+4)] + s/[8(s2+16)]. So the Laplace formula of cos4t, that is, L{cos4t} is given as follows. L{cos4t} = $\dfrac{3}{8s} + \dfrac{s}{2s^2+8} + \dfrac{s}{8s^2+128}$. Let us now prove the above Laplace transform formula of the fourth power of cost. What is the Laplace of cos4t Answer: … Read more
