    Need help on identities

    I am really struggling on how to approach this problem.

    Cos6 x + 3cos2 xsin2x + sin6x = 1

    Note: The numbers after the cos and sin are squared.

    So you mean the question is :
    \cos{6x}^2 + 3\cos{2x}\sin{2x} + \sin{6x}^2 = 1
    ?

    No its cos to the 6th power times x. The + 3cos squared times x times sin squared times x. thne + sin to the 6th power times x. I dont know how to make the numbers subscripts that is why it looks confusing.
