Question: Let F ( t ) = 3 t i + 3 c o s ( 3 t ) j - 2 e 6 t k

Let F(t)=3ti+3cos(3t)j-2e6tk and G(t)=3sin(2t)i-j-1tk, find F(t)G(t)
A.-3cos(3t)t-2e6t-(-3+6e6tsin(2t))+(-3t)-9cos(3t)sin(2t)
B.(-3cos(3t)t-2e6t)i-(-3+6e6tsin(2t))j+(-3t-9cos(3t)sin(2t))k
c.9tsin(2t)i-3cos(3t)j+2e6ttk
D.(-3cos(3t)t-2e6t-(-3+6e6tsin(2t))+(-3t)-9cos(3t)sin(2t))i
E.9tsin(2t)-3cos(3t)+2e6tt
Let F ( t ) = 3 t i + 3 c o s ( 3 t ) j - 2 e 6 t
