R. = [3 x 2 ][sin 2 (3 x 2 )] + [sin 2 (3 x 2 )] [ x 3 ] = [3 x 2 ][sin 2 (3 x 2 )] + [(2 sin(3 x 2 ))(cos(3 x 2 )(6 x )][ x 3 ] C. R. Feel free to ask me about the challenge question if you are curious. Can you ﬁnd a formula for the derivative of the product of three functions? We know: [ gh ] = [ g ] [ h ] + [ h ] [ g ] . What about: [ fgh ] =???...
