In `DeltaABC`, if `/_B=90^0`, prove that `tan (A/2) = sqrt((b-c)/(b+c))`

In Delta ABC, if /_C=90^(@), then prove that tan((A)/(2))=sqrt((c-b)/(c+b))=(a)/(b+c)

If tan((A)/(2))=sqrt((b-c)/(b+c)),/_B=

In a DeltaABC , if B=90^(@) , then tan^(2).(A)/(2) =

In any DeltaABC , prov "If in a "DeltaABC, /_C=90^(@)," then prove that sin"(A-B)=((a^(2)-b^(2)))/((a^(2)+b^(2)))

In DeltaABC , Prove that (s-a) tan (A/2)=(s-b) tan (B/2)=(s-c) tan (C/2)

In DeltaABC , prove that: sin(B-C)/(2)=(b-c)/(a).cosA/2

In DeltaABC , prove that: (a-b)/c=(sin(A-B)/(2))/(cosC/2)

If in a triangle A B C angle B=90^0 then tan^2(A/2) is (b-c)/a (b) (b-c)/(b+c) (c) (b+c)/(b-c) (d) (b+c)/a
