ln a triangle `ABC, B=90^@` then the value of `tan(A/2)=`

In a triangle ABC,B=90^(@) then the value of tan((A)/(2))=

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

If an a triangle ABC,b=3c and C-B=90^(@), then find the value of tan B

In triangle ABC ,prove that the maximum value of tan(A)/(2)tan(B)/(2)tan(C)/(2)is(R)/(2s)

(i) A,B and C are interior angles of a triangle ABC.Show that sin((B+C)/(2))=cos((A)/(2)) . (ii) If angleA=90^(@) , then find the value of tan((B+C)/(2)) .

In /_\ABC , if angleC = 90^@ ,. then find the value of tan A + tan B.

In any triangle ABC, the value of (b+c) tan ""A/2 tan ""(B-C)/(2)+ (c+a) tan ""B/2 tan ""(C-A)/(2) + (a+b) tan ""C/2 tan ""(A-B)/(2) is-
