Me solve this, use trigonometric identities to solve 2cos^2(θ)=sin(θ)+1 exactly for 0≤θ< 2π. if there is more than one answer, enter your answers as a comma separated list.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
