Answer 2

Heya!!

Tan ( A + B ) =

Tan A + Tan B

----------------

1 - Tan A × Tan B

=>

Tan A + Tan B = Tan ( A + B ) { 1 - Tan A × Tan B }

Tan π/12 + Tan π/6 = Tan 45 { 1 - Tan π/12 × Tan π/6 }

Q.NO 1

Tan π/12 + Tan π/6 + Tan π/12 × Tan π/6 = 1

L.H.S

Tan 45 { 1 - Tan π/12 × Tan π/6 } + Tan π/12 × Tan π/6

1 × ( 1 - Tan π/12 × Tan π/6 ) + Tan π/12 × Tan π/6

Becoz Tan 45 = 1

1 - Tan π/12 × Tan π/6 + Tan π/12 × Tan π/6

= 1 = R.H.S
