you can't call two different things the same variable and then add them like they are the same.

thats what i thought. but when i did it as tan(A+B) which would be tanA+tanb/1-tanAtanB it did not correspond with the answer my teacher gave which is -√3/3.
I think -sqrt(3)/3 is incorrect
what did you get?
maple is saying that isn't right. Let me work the problem.. one sec.
ok i got (-9sqrt(3)+8sqrt(5))/(-11)
thats what maple got too
ok so my numerator is right but my denominator is wrong. can you explain how you got the denominator?
my denominator was initially 1+sqrt(3)*sqrt(5)/2, so i multiplied top and bottom by the conjugate:
then in the denominator you get 1-15/4. In the numerator there was a common factor of 1/4 so i multiplied the denominator by 4:
ohhh never mind i got it. thanks soo much for your help!!!
