Question

LHS=Tan(pi upon 4 + tita)RHS=1-tan tita upon 1+tan tits prove RHS​

Answer 1

Answer:

Step-by-step explanation:let consider LHS

Tan(π/4+theta)

Asπ/4=45 degree

Hence apply rule of tan(A+B)=tanA+tanB/1-tanAtanB

Therefore tan(π/4+theta)=tanπ/4+tantheta/1-tanπ/4.tantheta

As tan(π/4)=1

Therefore it becomes

1+tantheta/1-1xtantheta which is 1-tantheta

Hence tan(π/4+theta)=1+tantheta/1-tantheta

Hope it helps
