# Why Can't I Solve This Simple Trig Equation?

In summary, the conversation is about someone seeking help with solving a simple trigonometry equation. They need to solve the equation 1 + cos(θ) = 2sin(θ) in order to solve another problem, but for some reason, they are struggling to figure it out. They are asking for ideas and advice, and mention that the assignment is due in the morning. The suggested steps to solve the equation are to square both sides, substitute for sin(2θ), substitute x = cos(θ), solve the resulting quadratic equation, determine all possible solutions for θ, and finally check each solution with the original equation.
for some reason i can't figure out how to solve this very simple trig equation.
$$1 + \cos{\theta} = 2\sin{\theta}$$ i need this so that i can solve something else. ANY IDEAS WOULD HELP ME OUT.

normally i can solve things like this but for some reason tonight i can't see what to do. to make matters worse this is due in the morning at 9am!

a) Square both sides.
b) Sub {1 - cos2(θ)} for sin2(θ).
c) Sub {x = cos(θ)}.
e) Determine all candidate "θ" solutions.
f) CHECK EACH candidate "θ" solution with ORIGINAL EQUATION.
