Solve the following differential equations using laplace transforms. assume zero initial conditions and that the forcing functions are zero prior to t=0-.a. x(t) +7x (t) =5cos2tb. x(t) + 8 x(t) + 25x (t) =10u (t )

(A)

(B)

Step-by-step explanation:

We have to find the Laplace transform

(a) x(t) + 7 x(t) = 5 cos2t

Taking Laplace of both side

(B)

Taking Laplace transform of both side

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
