(sin x+ secx)^2+(cosx+cosecx)^2
using (a+b)^2
sin^2+sec^2+2sinsec +cos^2+cosec^2+2cosec cos
sin^2+cos^2+l+tan^2+2sin sec +cot^2-1+2cosec cos
1+1+tan^2+2sin sec +cot^2-1+2cosec cos
1+tan^2+2sin sec +cot^2+2cosec cos
solve like this
using (a+b)^2
sin^2+sec^2+2sinsec +cos^2+cosec^2+2cosec cos
sin^2+cos^2+l+tan^2+2sin sec +cot^2-1+2cosec cos

1+tan^2+2sin sec +cot^2+2cosec cos
solve like this
