Answer (1 of 2): Partial fraction: It is the process of separating, decomposing or breaking up a rational function N(x)/D(x) [N(x) and D(x) are polynomials] into a group of simpler fractions. It is the converse to the process of fusing a group of fractions, connected by addition and subtraction, ...

May 26, 2020 · L−1{aF (s) +bG(s)} = aL−1{F (s)} +bL−1{G(s)} L − 1 { a F ( s) + b G ( s) } = a L − 1 { F ( s) } + b L − 1 { G ( s) } for any constants a a and b b. So, we take the inverse transform of the individual transforms, put any constants back in and then add or subtract the results back up.

The inverse Laplace transform is the transformation that takes a function in the frequency domain and transforms it back to a function in the time domain. This transformation is accomplished by rotating counterclockwise around a point on the unit circle by 90 degrees and then scaling down by a factor of -1 in the vertical direction.

Theorem 26.2 (linearity of the inverse Laplace transform) The inverse Laplace transform transform is linear. That is, L−1[c 1F 1(s)+c 2F 2(s)+···+c n F n(s)] = c 1L−1[F 1(s)] + c 2L[F 2(s)] + ··· + c nL[F n(s)] when each c k is a constant and each F k is a function having an inverse Laplace transform.
