Hey.
Could anyone help me solve the below please?
Using algebra, prove that for all real values x
(x-2)^2 > 8x -33 + 2 sin x cos x
Would you use substitute 2 sin x cos x for sin 2x, and then since you know that the max. and min. values of sin 2x (-1 and +1), rearrange to find x?
Edit: Probably should mention that the question is only 4 marks
