# y = 3sin (x) -in (3x) #

# y '= 3cosx- cos (3x) * 3 # #color (white) (ttttt # # "nag-aaplay ng panuntunan ng chain sa" kasalanan (3x) #

# y '= 3 (cosx-cos3x) #

Sagot:

# dy / dx = 3cosx-3cos3x #

Paliwanag:

# "tukuyin ang" sin3x "gamit ang" kulay (bughaw) "tuntunin ng chain" #

# "Given" y = f (g (x)) "then" #

# dy / dx = f '(g (x)) xxg' (x) larrcolor (asul) "chain rule" #

# y = 3sinx-sin3x #

# rArrdy / dx = 3cosx-cos3x xxd / dx (3x) #

#color (white) (rArrdy / dx) = 3cosx-3cos3x #
