1) a) find the laplace trans form of the following expression: e^7 (6+3t^2- 3 cos 4t +5 sin 2t) + 48(t -3) + u(t + 2) b) find the inverse laplace transform of the following expression e^-2s (4/s+1)

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
