I think this can be solved in this way I did like this only in exam 1)1/1+sin^theta+1/1+cos^2theta+1/1+sec^ 2theta+1/1+cosec^2theta 2)1/1+sin^2theta+1/1+cos^2theta+1/1+1/cos^2theta+1/1+sin^2theta By taking lcm 3)1/1+sin^2theta+1/1+cos^2theta+cos^2the ta/cos^2theta+1+sin^2theta/sin^2theta+1 By taking lcm 4)sin^2theta+1/1+sin^2theta+cos^2theta+1/ 1+cos^2theta 5)1+1=2
