I think that you're making this more complicated than it has to be. BP1=BP2. Can't you just use this to show that tanx=1?
How do you resolve this one?
What i got till now:
BP1= 16+12/tanx
BP2= 12+16tanx
-----------------------
BP1=BP2 = 16+12/tanx = 12+16tanx = (...) = 4tanx - 16tanx2 +12=0
Is it correct?
All you have to do is resolve the equation, find tanx, then sinx and cosx and subsitute them in C(x)?
Thanks in advance!
If then because it is given that .

Did you understand? In fact you could also solve this question without the use of trigonometry.
