Thread: 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 :

?

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.
