if p and q are the solutions of the equation atanx+bsecx,show that tan(A+B)=2ac/(a^2-c^2)

I am wondering what c is.

a,b and c are constants

just where is b?

also, atanx +bsecx=c,i missed c and i am sorry for that

The more I study your question, it is fraught with errors.

Are you certain you are not proving

Tan(P+Q)= 2ac/(a^2-c^2)

That is rather straightforward.

yeah one more mistake from my part it is to prove tan(p+q)=...

atanx bsecx

This is another answer -

We are going to elinamate 'b' (rember in this type of questions ordirnely elimanation is important) i gave a ans in pervious post now other.
P and q are roots therfore..
atanp bsecq

Arti and bobpursly got ur ans .
