( ^3(x)+ ^3(x) ^2(x) ^2(x) d x= )

Options

  1. A( (x)- cosec (x)+c )
  2. B( (x)+ (x)+c )
  3. C( cosec (x)- (x)+c )
  4. D( (x)- (x)+c )

Correct answer

A. ( (x)- cosec (x)+c )

Step-by-step solution

( aligned & ^3 x+ ^3 x ^2 x ^2 x d x & = ( x x+ x cosec x) d x & = x- cosec x+C aligned ) Hence, option (a) is correct.
