    Trigonometry Identity problem I been trying to solve all day

    Yeah I see what you mean Mark44, Teachers always tell you to double check doing what you just did. Maybe I need to start doing that more.

    Trigonometry Identity problem I been trying to solve all day

    wow. My head was so wrapped up in Identities I didn't even think to factor them in standard form (cos +1)(2cos+1)=0 Thank you for shining a light through this fogged up brain of mine

    Trigonometry Identity problem I been trying to solve all day

    hold on I think I understand now. (3 cos(x)+1)(2cos^2(x))= 0, the solve those two for 0

    Trigonometry Identity problem I been trying to solve all day

    OK so I get the following 3 cos(x) + 3 = 2 - 2 cos^2(x) 3 cos(x) + 1 + 2 cos^2(x)=0 I tried this variation before, but I was unsure of what to do with the 1+2 cos^2(x) part. or maybe I'm just doing something wrong with the distribution and movement of the right side.

    Trigonometry Identity problem I been trying to solve all day

    Homework Statement solve 3cos(x) + 3 = 2 sin^2(x) where 0 <= x < 2piHomework Equations The Attempt at a Solution 3(cos(x) + 1) = 2 sin^2(x) 3(cos(x) + 1) = 2 (1- cos^2(x)) I've tried this variation, and a couple others but it just does not pan out. Please help. Oh yeah we have a real...
