if you really mean 0612, then no.
Otherwise, it is always possible to solve
2cos(x) = n
if |n/2| <= 1
If possible find a solution to 2 cos(theta)=-0612.
theta=

That doesnt really help me solve for theta
well, in that case, as you have written it, there is no solution. There is no θ such that
cosθ = -306
If you can figure out what you really meant, learn about the 2nd function for the cos button on your calculator, and the arccos(θ) or cos-1θ function
