Use Theorem 7.1.1 to find {{f(t)}. (Write your answer as a function of s.) f(t) = e cosh(t) Rf(t) } = Find {{f(t)} by first using a trigonometric identity. (Write your answer as a function of f(t) = sin(3t) cos(3t) {{f(t)} = Find {{f(t)} by first using a trigonometric identity. (Write your answer as a function of s.) f(t) = sin(3t + 6) {{f(t)} = Use Theorem 7.1.1 to find _{f(t)}. (Write your answer as a function of s.) f(t) = 1+ e3t Rf(t) }
