Please find tan(B+C) given that sin C= , with C in quadrant 2, and sin B= , with B in quadrant 4.
The correct answer is
I have fount that tan C= and tan B=
+ over 1-
Is this correct? What do I do next to get the correct answer?
Thank you

umm...you don't have a lot of options here. combine the fractions in the numerator and denominator and simplify (note: you may need to conjugate). for the record, i used a different formula and got the answer, it's still a pain to simplify though. i always have trouble remembering the addition formula for tangent, so i used . but i'm sure you'll get the answer doing it your way. your values for tanB and tanC are correct
Hello, oceanmd!
You're doing great !!
