Question

( cos theta+cos theta=sqrt{2} sin thetaleft[begin{array}{c}cos [90-theta]=sin theta sin (90-theta)=cos 0end{array}right. )
( 2 cos theta=sqrt{2 sin theta} )
( frac{2}{sqrt{2}}=tan theta )
( tan theta=sqrt{2} )
( operatorname{cosec} theta=frac{1}{sin theta} )
( =frac{sqrt{3}}{sqrt{2}} )

# (93) Sim (90-0) + cord=d2 Cos (90-0) find value coseco
