if tan 3. tan 6=1 then the value of thita

Answers

Answered by TheLostMonk

let A = thita

tan3Atan6A = 1 ----(1)

tan(3A+6A) = 1

tan9A = 1

tan9A = tan45°

9A = 45°

A = 45 °/9 = 5°

A = 5°

hence value of thita = 5°

or if you want to check that your answer is correct or not .then put value in "A " eq.(1)

tan3(5)tan6(5) = 1

tan15tan30 = 1

tan(15+30 ) = 1

tan45° = 1

1 = 1

L.H.S =R.H.S

hence your value of thita(A) is correct.

hope it helps !
thank you!

TheLostMonk: i said you could add then by taking out tan(common ) if there is value in the other side =1 ..etc

barry54: okk..thnk u bro..this is so exceptional

barry54: it was nice to talk with you

TheLostMonk: otherwise in some other cases we use tan(A+B) = tanA +TanB /1 - tanA tanB

TheLostMonk: thank you ! wc

barry54: it will make complex one..

barry54: but u made ryt one

TheLostMonk: yes ! thats why i did'nt use it .

TheLostMonk: plz like this post if it helped , may i be wrong ,but i did it as per my perception ,or if it will be wrong then you make me aware about that ny commenting here
