if `cos^2alpha-sinalpha=1/n` then `alpha`

(1-cos alpha)/(sinalpha)=tan(alpha/2)

If (2sinalpha)/({1+cos alpha+sin alpha})=y, then ({1-cos alpha+sin alpha})/(1+sin alpha)=

Find A^2 if A = [(cos alpha, sinalpha),(-sin alpha, cos alpha)]

If (2 sin alpha)/(1 + cos alpha + sin alpha) = 3/4 , then the value of (1 + cos alpha + sinalpha)/(1 + sin alpha) is equal to
