So you just want someone else to do them for you?
hi guys , i am a high school student , and i have a trigonometry test tomorrow . i would appreciate every help from you.
for now i can't solve these trigonometry equations.
they are mashing up my mind
1) sin^{2}x + sinx * cosx = 1
2)1+cosx + cos(x/2) =0
3) 1 + cos(π +x ) + cos(π/2 + x/2) =0
I am doing a whole summary of the trigonometry chapter at the moment , so that i'll be more prepared for tha exam. These 3 equations were the only ones i couldn't solve , i asked help from my parents , my brother but they couldn't solve it either. I wasn't left with much choices so i went online and posted them here and i think this is the most adequate place to do it. No, i'm not asking someone else to do them for me . I just want a hint, a way of doing them so that i can learn something and put it to use later.
