tan69 + tan66 + 1= tan69.tan66 |
|
Answer» =>We know that, tan(135)=tan(180-45)= -tan45= -1 =>So, tan(135)=-1 =>tan(66+69)= -1 => (tan66+tan69)/(1-tan66.tan69)=-1 => tan66+tan69= -1+tan66.tan69 =>tan66+tan69+1=tan69.tan66...Hence, proved. We know that tan(69+66)=tan69 + tan 66/1-tan69.tan66Taking rhs,Tan69 + tan66=1 -tan69.tan661-tan69-tan66=tan69.tan66Vo kabhi proof nhi hoga |
