2E: Chain Rule (Composition)
Given the following functions of x, write the equation for the derivative function. Remember to apply the constant, linear, product, quotient, and most importantly, the chain rule. Please do NOT simplify your answers. 1. ( ) ( )xxf 3sin= ( ) =xf ' 2. ( ) ( )( )43sin xxg = ( ) =xg' 3. ( ) ( )( ) xxxh 103sin 4 += ( ) =xh' 4. ( ) ( )( )[ ]24 103sin xxxi += ( ) =xi'
