Laplace Transform f(t) = cos(t), 0 ≤ t < 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!!

What number is greatest?<br><br> 2 2/3,2.67,2 3/5,2.49

Anettt [7]

As a decimal, 2 2/3 is 2.67
2 3/5 is 2.6

So, the greatest is 2 2/3 and 2.67 because they are equivalent

To solve the linear equation , the first step is to multiply each side by the least common denominator of all the fractions in

cupoosta [38]

Answer:

Step-by-step explanation:

The least common denominator of the 7, 6, 12, which are the denominators of the fractions in the given linear equation, is the least expression or number that is divisible by 7, 6, 12.

To find the LCD, express each number as factors of itself as follows:

$7 = 1*7$
