In any triangle ABC, show that : 2a sin (B/2) sin (C/2)=(b+c-a) sin (A/2)

In any triangle ABC sum (sin^2A+sinA+1)/sinA is always greater than or equal

In an isosceles right angled triangle ABC, /_B=90^0, AD is the median then (sin/_BAD)/(sin/_CAD) is (A) 1/sqrt(2) (B) sqrt(2) (C) 1 (D) none of these

If in a Delta ABC, /_ C=90^@, then the maximum value of sinA sinB is
