Question

If sinx-13, siny = 4 x belongs to Ind
quadrant and y belongs to the first quadroant.
Find the value of sin Gety), Colorth cos(x-y),
tan (arty)​

Answer 1

Answer:

the value sinx =4 , cos( x-y) , tan(arty) ={which means the value of sin should be convert into cos thita , cosx +siny( cosy) =cos x+sincosy=sinx(cos y) =1so the value of (arty) is 1 hence proved..
