Mechanical Engineering > GATE 2026 > Laplace Transform
Let f(t) be a function of t defined for all positive values of t. The Laplace transform of f(t) denoted by L{f(t)} = ∫0∞ e−stf(t)dt, provided that the integral exists where s is a parameter which may be a real or complex number.
The Laplace transform of f(t) = sin 2t sin 4t is
A
16s/((s2+4)(s2+36))
B
32s/((s2+4)(s2+36))
C
16/((s2+4)(s2+36))
D
32/((s2+4)(s2+36))

Correct : d
