In `DeltaABC`, If `C=90^@` then, `(a^2+b^2)/(a^2-b^2)sin (A-B) =`

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

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

If in a DeltaABC, (a^(2)-b^(2))/(a ^(2)+b^(2))=(sin (A-B))/(sin (A+B)), then the triangle is

In DeltaABC, (a^(2)+b^(2))/(a^(2)-b^(2))=(sin(A+B))/(sin(A-B)) , prove that the triangle is isosceles or right triangle.

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 show that (b^(2)-c^(2))/(a^(2))=(sin(B-C))/(sin(B+C))

In any DeltaABC , prove that : (b^2 - c^2)/a^2 = (sin (B-C))/(sin(B+C))

In any DeltaABC , prove that, (b^(2)-c^(2))/a^(2)sin2A+(c^(2)-a^(2))/b^(2)sin2B+(a^(2)-b^(2))/c^(2)sin2C=0 .

If A+B+C=90^(@) then sin^(2)A+sin^(2)B+sin^(2)C=
