How to prove that 1/2(1+sin^2 x) + 1/2(1+cos^2 x) + 1/2(1+sec^2 x)+ 1/2(1+cosec^2 x) = 1

What have you tried so far? We need to know where you are stuck before we can help.

I tried to combine them
It must be \(\displaystyle \frac{1}{2(1+ sin^2 x)}+ \frac{1}{2(1+ cos^2 x)}+ \frac{1}{2(1+ sec^2 x)}+ \frac{1}{2(1+ cosec^2 x)}= 1\) because \(\displaystyle \frac{1}{2}(1+ sin^2 x)+ \frac{1}{2}(1+ cos^2 x)+ \frac{1}{2}(1+ sec^2 x)+ \frac{1}{2}(1+ cosec^2 x)= 1\) is not true.How to prove that 1/2(1+sin^2 x) + 1/2(1+cos^2 x) + 1/2(1+sec^2 x)+ 1/2(1+cosec^2 x) = 1
