sin 2x = sin (x - 4)
2x = x-4, π - (x-4), 2π + (x-4), 3π - (x-4), 4π + (x-4), 5π - (x-4)
=> Generate round the quadrant
x = -4, (π+4)/3, 2π-4, (3π+4)/3, 4π-4, (5π+4)/3
x = -4, 2.38, 2.28, 4.47, 8.57, 6.57
since 0 ≤ x ≤ 5,
x = 2.28, 2.38, 4.47 (do check for careless mistakes)

Thanks for the prompt reply...Anyway sketching out the curve
reveals that there is a 4th solution at about x= 0.2 to 0.3. Any
help again?
