(sin²22°+sin²68°/cos²22°+cos²68°)+sin63°+cos63°*cos27°
=[sin²(90°-68°)+sin²68°/cos²(90°-68°)+cos²68°]+sin63°+cos(90°-27°)*sin27°
=cos²68°+sin²68°/sin²68°+cos²68° + sin63°+sin27°*sin27°
=1/1+sin63°+sin27°*sin27°
=sin63°+sin27°*cos27°
=sin63°+sin²27°
I think the question is a bit incomplete.
But if it is correct, then this is ur answer.
