Question

laplace please

Answer 1

did you try partial fractions ?

Answer 2

do you know what is partial fractions ?

Answer 3

no

Answer 4

laplace

Answer 5

\(\large F(s)=\dfrac{4}{(s+2)(s+1)^2}=\dfrac{A}{s+2}+\dfrac{B}{s+1}+\dfrac{C}{(s+1)^2}\)
thats partial fractions,
you need to find values of A,B and C
can you ?

Answer 6

dw:1364293585491:dw|

Answer 7

what ?

Answer 8

that square is not suppose to be threre

Answer 9

but i am not able to see your diagram in your previous reply.

Answer 10

you need to find A,B, C in
\(\large F(s)=\dfrac{4}{(s+2)(s+1)^2}=\dfrac{A}{s+2}+\dfrac{B}{s+1}+\dfrac{C}{(s+1)^2}\)
so that you get the terms in standard form and thereby can take inverse laplace transform of each term.

Answer 11

\(\large F(s)=\dfrac{4}{(s+2)(s+1)^2}=\dfrac{A}{s+2}+\dfrac{B}{s+1}+\dfrac{C}{(s+1)^2} \\ \large \implies 4 =A(s+1)^2+B(s+1)(s+2)+C(s+2)\)
to find A, put s=-2
to find C, put s=-1
to find B, put any other values of s, say s=0.
and tell me what you get A,B,C values.

Answer 12

continue the calculation

Answer 13

blessing, you need to participate in the solution process instead of telling people to do the work for you.

hartnn has started the process, and if you do not know what they are doing,m then you are not prepared to do a Laplace

Answer 14

@amistre64
if ii know it will not post it
