Question

if tan theta + tan 2 theta + tan theta into 10 to theta equals to 1 then theta is

Answer 1

tan@+tan2@[email protected]@=1,

then

tan@+tan2@[email protected]@,

we can write it as

(tan@+tan2@)/([email protected]@) =1,


then it becomes

tan(@+2@)=1,

tan3@=1,

tan3@=tan45°,

then

3@=45°,

@=45°/3
