X(S)=A(Scos ‚Äö√†√∂‚àö‚â§-‚âà√¨‚àö¬¢ sin‚Äö√†√∂‚àö‚â§)/(S2-‚âà√¨‚àö¬¢2 )

TuteeHUB · Answer

X(S)=A(Scos ‚Äö√†√∂‚àö‚â§+‚âà√¨‚àö¬¢ sin‚Äö√†√∂‚àö‚â§)/(S2+‚âà√¨‚àö¬¢2 )

TuteeHUB · Answer

X(S)=A(Scos ‚Äö√†√∂‚àö‚â§+‚âà√¨‚àö¬¢ sin‚Äö√†√∂‚àö‚â§)/(S2-‚âà√¨‚àö¬¢2 )

X(S)=A(Scos ‚Äö√†√∂‚àö‚â§-‚âà√¨‚àö¬¢ sin‚Äö√†√∂‚àö‚â§)/(S2+‚âà√¨‚àö¬¢2 )

1.	Let us assume x (t) = A cos(‚âà√¨‚àö¬¢t + ‚âà√¨‚àö√∫), then the Laplace transform of x (t) is?$
A.	X(S)=A(Scos ‚Äö√†√∂‚àö‚â§-‚âà√¨‚àö¬¢ sin‚Äö√†√∂‚àö‚â§)/(S<sup>2</sup>-‚âà√¨‚àö¬¢<sup>2</sup> )
B.	X(S)=A(Scos ‚Äö√†√∂‚àö‚â§+‚âà√¨‚àö¬¢ sin‚Äö√†√∂‚àö‚â§)/(S<sup>2</sup>+‚âà√¨‚àö¬¢<sup>2</sup> )
C.	X(S)=A(Scos ‚Äö√†√∂‚àö‚â§+‚âà√¨‚àö¬¢ sin‚Äö√†√∂‚àö‚â§)/(S<sup>2</sup>-‚âà√¨‚àö¬¢<sup>2</sup> )
D.	X(S)=A(Scos ‚Äö√†√∂‚àö‚â§-‚âà√¨‚àö¬¢ sin‚Äö√†√∂‚àö‚â§)/(S<sup>2</sup>+‚âà√¨‚àö¬¢<sup>2</sup> )
