( ^3(x) ^3(x) d x= )
Options
- A( ^4(x)- ^6(x)+c )
- B( ^4(x)- ^6(x)+c )
- C( 1 4 ^4(x)- 1 6 ^6(x)+c )
- D( 1 4 ^4(x)- 1 6 ^6(x)+c )
Correct answer
C. ( 1 4 ^4(x)- 1 6 ^6(x)+c )
Step-by-step solution
( aligned & ^3 x ^3 x d x & = ^3 x x (1- ^2 x ) d x aligned ) Let (t= x d t= x d x ) ( aligned & t^3 (1-t^2 ) d t= (t^3-t^5 ) d t & t^4 4 - t^6 6 +C= ^4 x 4 - ^6 x 6 +C aligned )
