Answer 2

As given in this question that cosx + cos²x=1 then use the identity

As given in this question that cosx + cos²x=1 then use the identitysin²x+cos²x=1

As given in this question that cosx + cos²x=1 then use the identitysin²x+cos²x=1and the equation become as

As given in this question that cosx + cos²x=1 then use the identitysin²x+cos²x=1and the equation become ascosx +1 -sin²x = 1.

As given in this question that cosx + cos²x=1 then use the identitysin²x+cos²x=1and the equation become ascosx +1 -sin²x = 1.cosx = sin²x

As given in this question that cosx + cos²x=1 then use the identitysin²x+cos²x=1and the equation become ascosx +1 -sin²x = 1.cosx = sin²xcos²x=sin⁴x

As given in this question that cosx + cos²x=1 then use the identitysin²x+cos²x=1and the equation become ascosx +1 -sin²x = 1.cosx = sin²xcos²x=sin⁴xand back to the given equation you are left with sin²x+sin⁴x=1.
