Use the product rule, you'll always know to use the product rule when there are two factors of 'x' or 'y' or whatever. In this case you would split it up into x and sin 2x

use the product rule.

how will.you identify when to use product rule?
when u have to functions of x as a product always use product rule like;
y = f (x) * g (x) Then use product rule. in this case x is a function of x and also sin x is function of x and they r multiplied so product rule.

NOTE: when differentiating 2sin x u won't use product rule because yes u have two products 2 and sin x but 2 is not a function of x so u can't use product rule.....SO TO USE PRODUCT RULE....BOTH FUNCTIONS MUST BE OF X.

Hope I helped
