Solve the equation

2+log2⁡(cos⁡θ)=12log2⁡(3)−log2⁡(sin⁡θ),0≤θ≤2π

Recall that

sin⁡(2θ)=2sin⁡θcos⁡θ

Once you have your solutions, you need to select only the ones where both cos⁡θ and sin⁡θ are positive, so that log⁡(cos⁡θ) and log⁡(sin⁡θ) are defined.


The product of the solutions can be expressed as πnm for n,m∈N.

Give the value of

nm
