Laplace Transform f(t) = cos(t), 0 ≤ t &lt; π 0, t ≥ π Complete the integral(s) that defines ℒ{f(t)}. ℒ{f(t)} = π dt + [infinity
tensa zangetsu [6.8K]

Answer:

L[f(t)=s/(1+s^2)]

Step-by-step explanation:

The Laplace Transform is given by the integral:

L[f(t)]=\int_0^\infty e^{-st}\ f(t)dt

by replacing f(t)=cost we get

\int_0^{\infty} e^{-st}costdt=[e^{-s(\infty)}sin(\infty)-1sin(0)]-s\int_{0}^{\infty}e^{-st}sintdt\\\\=0+s[-e^{-s(\infty)}cos(\infty)+e^{s(0)}cost(0)-s\int_0^{\infty}e^{-st}costdt]\\\\=0+s[0+1-s\int_0^{\infty}e^{-st}costdt]=s-s^2\int_0^{\infty}e^{-st}costdt\\\\(1+s^2)\int_0^{\infty}e^{-st}costdt=s\\\\\int_0^{\infty}e^{-st}costdt=\frac{s}{1+s^2}

hope this helps!!

Find 4 consecutive even numbers whose sum is 156?
faust18 [17]
X + (x + 2) + (x + 4) + (x + 6) = 156
       x + x + x + x + 2 + 4 + 6 = 156
                                 4x + 12 = 156
                                       - 12   - 12
                                         4x = 144
                                          4        4
                                           x = 36
       x = 36
x + 2 = 38
x + 4 = 40
x + 6 = 42
