Answers

Answered by Sm1840635

Just take tan on both sides and use formula tan(A+B)

Answered by adityakjha24

A+B = π /4 =45°

TAKE TAN TO BOTH SIDES

Tan(A+B )= Tan45°

tanA+tanB/1-tanAtanB =1

1-tanAtanB=tanA+tanB
1= tanA + tanB + tanA.tanB

1+1=1+tanA+tanB+tan.AtanB

2=(1+tanA)(1+tanB)

adityakjha24: hope this will help... if any query feel free to ask

rachit751: Please explain from last 2 line

adityakjha24: ok

adityakjha24: add 1 to both side.. this will not create any difference in equation...after that take common

adityakjha24: 1(1+tanA) + tanB (1+ tanA) = (1+tanA)(1+tanB)

rachit751: Oh I got it thanks

adityakjha24: always wlcm...foloow me for any kinda help in maths
