ya because TAN(pi/4+x)=1+tanx/1-tanx
and TAN(pi/4-x)=1-tanx/1+tanx
from this you get your answer

When we expand it we get...Tan π/4 + Tan x / 1- Tan π/4 × Tanx / Tan π/4 - Tanx / 1+ Tanπ/4 × Tan x Which implies 1 + Tanx / 1- Tanx / 1- Tanx / 1+ Tanx Which equals (1+Tanx)2/ (1-Tanx)2Equals (1+Tanx / 1- Tanx)2
