Web19 okt. 2024 · Answer: The Laplace transform of t sin at is 2as/ (s 2 +a 2) 2. Proof: Put f (t) = t sin (at) in the above formula (∗). Note that L {sin at} = a/ (s 2 +a 2 ). So the Laplace transform of t sin (at) by the above formula (∗) is equal to L { t sin ( a t) } = – d d s ( a s 2 + a 2) = – ( s 2 + a 2) d d s ( a) − a d d s ( s 2 + a 2) ( s 2 + a 2) 2 WebIf x = e t sin t, y = e t cos t, t is a parmeter then d 2 y d x 2 at t = π is equal to A 2 e - π B - 2 e - π C 0 D None of these Solution The correct option is A 2 e - π Explanation for the …
