We know that, tan(c-b) = (tan c – tan b)/(1+tan c * tan b),
So, (1+tan c * tan b) = (tan c – tan b) / tan (c-b),
Put c= x+ $\large \theta$ , b=x,
(1+tanx * tan(x+ $\large \theta$ )) = (tan(x+ $\large \theta$ ) – tan x) / tan(x+ $\large \theta$ -x) = (tan(x+ $\large \theta$ ) – tan x) / tan $\large \theta$ ,
Now , seperate the two terms in 2 diff integrals and solve.
