If median CD of ∆ABC is perpendicular on AC then show that 2 tan A +tanC =0

Question

Arun · Answer

Dear Anjali When we draw the median CD then, you will see that- In Triangle BCD use sine rule c/2 sinA /sin(180-C-A) = c/2 /sin(C-90) sinA/sin(A+C) = -1/cosC sinA cosC = -sin(A+ C) sinA cosC =-[sinAcosC + cosA sinC] 2tanA +tanC =0 Regards Arun (askIITians forum expert)
