Oct 29, 2020 ... Rewrite the sum as a product. sin(3x) + sin(7x) · sin(3x) + sin(7x)= sin(7x)+sin(3x) · sin(3x) + sin(7x). sin 3x = sin(2x + x). = sin 2xcosx + cos 2xsin x using the first addition ... Note that by using these formulae we have written sin 3x in terms of sin x (and its ... d/dx(4 sin (3x)). = 4d/dx(sin (3x)). = 4 × 3 cos (3x)). = 12 cos (3x)). (c)y = e−2x.
