Make use of the formula for tan(A+B)
OpenStudy (kayc):
is it possible that when i use tan(A+B) it becomes just tanA+tan B instead of tanA+tanB/1-tanAtanB ?
OpenStudy (asnaseer):
how?
OpenStudy (kayc):
like just multiplying tan in with the A+B instead of using the full equation
OpenStudy (asnaseer):
no that is incorrect - there is only one correct expansion for tan(A+B). tan(A+B) is not equal to tan * (A+B)
