Q. the value of `tan^-1(a/(b+c))+tan^-1(b/(c+a))`, if `/_=90^@` in triangle ABC, is

Q. the value of tan^-1(a/(b+c))+tan^-1(b/(c+a)) , if /_C=90^@ in triangle ABC, is

in triangle ABC,tan A+tan B+tan C=

If in triangle ABC, C = 90^circ then prove that tan^(-1) (a/(c+b)) + tan^(-1) (b/(a+c)) = pi/4 .

If C is a right angle in the triangle ABC, show that, tan^(-1) 'a/(b+c)' + tan^(-1) 'b/(c+a)' = pi/4 .

If angle A = 90 ^(@) in the triangle ABC, then tan ^(-1) (( c )/(a+b)) + tan ^(-1) ((b)/(a+c)) is equal to : a)0 b)1 c) (pi)/(4) d) (pi )/(6)

In triangle ABC, if r_(1)=3r, then the value of tan((A)/(2))(tan((B)/(2))+tan((C)/(2))) is equal to

Given a triangle Delta ABC such that sin^(2)A+sin^(2)C=1001.sin^(2)B .Then the value of (2(tan A+tan C)*tan^(2)B)/(tan A+tan B+tan C) is
