数学啊 啊啊啊

（e的-2x 次方）乘sin(3x-π/3)的导数怎么求啊？

Answer 1

-2（e的-2x 次方）乘sin(3x-π/3)+3（e的-2x 次方）乘cos(3x-π/3)

Answer 2

[e^(-2x )*sin(3x-π/3)]'= [e^(-2x )]'*sin(3x-π/3)+e^(-2x )*[sin(3x-π/3)]'

[e^(-2x )]'= -2e^(-2x )

[sin(3x-π/3)]'= 3cos(3x-π/3)

所以[e^(-2x )*sin(3x-π/3)]'= -2e^(-2x )*sin(3x-π/3)+e^(-2x )*3cos(3x-π/3)
