take the derivative of that one, using the product rule

Answer 2

@satellite73 it will be -2cos(x)sin(x)

Answer 3

@genius12 so the derivative of -2cos(x) sin(x) , and i got -2 cos(2x)

Answer 4

@satellite73 ?

Answer 5

@jazy should i now take the derivative of -2 cos(2x) ? or

Answer 6

which one :
