Best ResponseYou've already chosen the best response.0i know for stuff like :x^3+x^2, it's just = 3x^2+2x but how would you do it one by one for SIN and COS??

Best ResponseYou've already chosen the best response.0aaak I subtracted should be added: f'g + g'f f=2 f'=0 g=sinx g'=cos x 0*sinx + cosx * 2 but for reasons known only to my brain I wanted to subtract so first part is 2 cosx no negativity

Best ResponseYou've already chosen the best response.0right so 2sinx is two times sine x ya? how come no multiplication rule? Ah because it is not (2x)sinx......so should treat it like coefficient in 3x^2
