do NOT integrate anymore. Just use the Laplace Formulas directly. If needed, apply the trigonometric identities first [ For example, cos(A+B) = cosAcosB - sinAsinB ] before using the Laplace formulas.

ANSWER ITEM 5 AND 7 ONLY
Transcribed Image Text:5. f(t)=-3t*e0.s* +3.8t²e²4*
6. f(1)=-e" sin (21 + a)
7. f(1)=3e" cosh (In 21) in two ways.
Note: Please DISREGARD the phrase "in two ways" in item #7.
Equations that give the relation between different trigonometric functions and are true for any value of the variable for the domain. There are six trigonometric functions: sine, cosine, tangent, cotangent, secant, and cosecant.
