1. Maths C2 help?
Im stuck on second part of this question

Write down the exact values of cos1/6π and tan 1/3π (where the angles are in radians). Hence verify that x=1/6π is a solution of the equation 2cosx = tan2x

Ive got cos1/6π= √3/3 and tan1/3π=√3

Is it trig functions? any help would be appreciated

I don't really understand what you mean.

Have you tried plugging into the equation?

Also, you've said that . This is not correct.

Yes, it is a trig function.

Remember,

Input in , and show that both RHS and LHS are equal.

sorry did mean cos1/6π= √3/2
Thanks for the reply I think I was getting confused by the wording, made it sound harder than it is (I think)
