If 11sin^2 theta-cos^2 theta+4sin theta-...

If `11sin^2 theta-cos^2 theta+4sin theta- 4=0, 0^@< theta<90^@`, then what is the value of `(cos2 theta+cot2 theta)/ (sec2 theta-tan2 theta)` ?
यदि`11sin^2 theta-cos^2 theta+4sin theta- 4=0, 0^@< theta<90^@`, है, तो `(cos2 theta+cot2 theta)/ (sec2 theta-tan2 theta)` का मान क्या होगा ?
