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

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

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

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

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

If in a DeltaABC , c = 3b and C - B = 90°, then tanB=

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

If a=(b-c)Sec theta , Prove that tan theta=(2sqrt(bc))/(b-c)Sin(A)/(2)

In any Delta ABC, prove that :tan((A)/(2)+B)=(c+b)/(c-b)tan((A)/(2))
