Question:How to get Maple to write vector times scalar without putting the scalar in the vector?

In the code below, expr is a variable that is a vector times a cosine. Maple performs the multiplication of the vector times the scalar and writes it all as a single vector.

For didactical purposes, I wish for Maple to write out the vector times the cosine, without putting the cosine in the vector.

How is this accomplished?

v := `<,>`(`<|>`(a), `<|>`(b))

Matrix(%id = 36893488152047505644)

 (1)

expr := v*cos(t*theta+phi)

Matrix(%id = 36893488152047493236)

 (2)

expr := 'v'*cos(t*theta+phi)

v*cos(t*theta+phi)

 (3)

NULL
