( begin{array}{l}qquad begin{aligned} P &=sin theta+cos theta & q=sec theta+operatorname{cosec} theta p^{2} &=1+2 sin theta cos theta end{aligned} operatorname{RHS}=9left(p^{2}-1right) & (sec theta+cos e cos (x+2 sin theta cos theta-lambda) & =left(frac{1}{cos theta}+frac{1}{sin theta}right) 2 sin theta cos theta=2[sin theta+cos theta]=R H Send{array} )
