Question

evaluate tanpi/12+tan7pi/4 / 1-tanpi/12tan7pi/4

Answer 1

Make use of the formula for tan(A+B)

Answer 2

is it possible that when i use tan(A+B) it becomes just tanA+tan B instead of tanA+tanB/1-tanAtanB ?

Answer 3

how?

Answer 4

like just multiplying tan in with the A+B instead of using the full equation

Answer 5

no that is incorrect - there is only one correct expansion for tan(A+B).
tan(A+B) is not equal to tan * (A+B)
