Given that `a , b , c ,` are the side of a ` A B C` which is right angled at `C ,` then the minimum value of `(c/a+c/b)^2` is

If DeltaABC is right angled at C , then the value of cos(A+B) is

If a,b and c are the side of a triangle,then the minimum value of (2a)/(b+c-a)+(2b)/(c+a-b)+(2c)/(a+b-c) is 3 (b) 9(c)6(d)1

If a,b,c are the sides of a triangle,then the minimum value of (a)/(b+c-a)+(b)/(c+a-b)+(c)/(a+b-c) is equal to (a)3(b)6(c)9(d)12

If a , b , c are the sides of triangle , then the least value of (a)/(c+a-b)+(b)/(a+b-c)+(c )/(b+c-a) is

If A, B, C be an acute angled triangle, then the minimum value of tan^(4)A+tan^(4)B+tan^(4)C will be

Let a, b, c be the sides of a triangle and let A, B, C be the respective angles. If b+c=3a, then find the value of the ratio cos((B-C)/2)/cos((B+C)/2)

If a,b,c are three positive real numbers then the minimum value of the expression (b+c)/(a)+(c+a)/(b)+(a+b)/(c) is
