If the roots of `x^2 + ax + b = 0` are `sec^2 pi/8` and `cosec^2 pi/8` then which of the following is correct?

If the roots of x^(2)+ax +b = 0 are sec^(2)(pi)/(8) and coses^(2)(pi)/(8) , then the numerical value of (a+b).

If the roots of x^(2)+ax +b = 0 are sec^(2)((pi)/(8)) and coses^(2)(pi)/(8) , then the numerical value of (a+b) .

If the roots of x^(2)+ax +b = 0 are sec^(2)(pi)/(8) and coses^(2)(pi)/(8) , then the numerical value of (a+b).

Given a^(2)+2a+csc^(2)((pi)/(2)(a+x))=0 then,which of the following holds good

The number of solution of sec^(2) theta + cosec^(2) theta+2 cosec^(2) theta=8, 0 le theta le pi//2 is

The number of solution of sec^(2) theta + cosec^(2) theta+2 cosec^(2) theta=8, 0 le theta le pi//2 is

The number of solution of sec^(2) theta + cosec^(2) theta+2 cosec^(2) theta=8, 0 le theta le pi//2 is

If sec alpha and cosec alpha are the roots of the equation x^(2)-ax+b=0, then

If sec alpha and cosec alpha are the roots of the equation x^(2)-ax+b=0, then
