In any `DeltaABC`, if `B=60^0`, then prove that `(c-a)^2 = b^2 -ca`

In any Delta ABC, if B=60^(@), then prove that (c-a)^(2)=b^(2)-ca

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

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 any DeltaABC , prove that : (b^2 + c^2 - a^2)/(c^2 +a^2 -b^2) = (tan B)/(tan A)

For any DeltaABC , prove that a(b cos C -c cos B) = b^2 - c^2

In any DeltaABC , prove that : (b^2 -c^2) sin^2 A + (c^2 -a^2) sin^2 B + (a^2 - b^2) sin^2 C = 0

In any DeltaABC , prove that a(bcosC-c cosB)=(b^(2)-c^(2))

In any DeltaABC , prove that ((b-c))/acosA/2=sin((B-C))/2

In any DeltaABC , prove that : (b-c)/a cos^2 (A/2) + (c-a)/b cos^2 (B/2) + (a-b)/c cos^2 (C/2) = 0
