Solve ( (x)+ (x)= 3 , x [0,2 ] )
Options
- A( 3 )
- B( 6 )
- C( 13 6 )
- D( 6 13 )
Correct answer
B. ( 6 )
Step-by-step solution
Given trigonometric equation is ( aligned & x+ x= 3 , x [0,2 ] & x- x= 1 3 aligned ) So, (2 x= 3 - 1 3 ) ( 2 x= 2 3 x= 1 3 x= 6 ) or ( 7 6 ) Hence, option (b) is correct.
