from (secsquare theeta )(cosecsquare theeta) =(1+tansquare theeta)(1+cotsquare theeta)=1+cotsquare theeta+tansquare theeta+tansquaretheeta*cotsquare theeta=cotsquare theeta+tansquare theeta+2(since secsquare theeta- tansquare theeta=1 and cosecsquare theeta- cotsquare theeta=1and cotsquare theeta*tansquare theeta=1)
