Prove That (sin A+cosec A)^2+(cos A+sec A)^2= 7+ tan^2 A+ cot^2 A

Prove That (sin A+cosec A)^2+(cos A+sec A)^2= 7+ tan^2 A+ cot^2 A
#Trigonometry
(sin a+cosec a)^2+(cos a+sec a)^2=7+tan^2a+cot^2a, prove that (sin a+cosec a)^(2)+(cos a+sec a)^(2)=7+tan^(2)a+cot^(2)a, √(1+ sin a)/(1- sin a)= sec a+ tan a, cos a-sin a+1/cos a+ sin a-1 =cosec a+ cot a, (tan a/1-cot a) + (cot a/1-tan a) =1+sec a cosec a

In this session I will be starting with Exercise 8.4 Q5 (viii) of chapter "Trigonometry ".
