" 8.If "a=(b*c)sec q," prove that "tan q=(2sqrt(bc))/(b*c)sin(A)/(2)

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

In Delta ABC if a=(b-c)sec theta then (2sqrt(bc))/(b-c)sin((A)/(2))=

In Delta ABC if a=(b-c)sec theta then (2sqrt(b)c)/(b-c)sin((A)/(2))=

In DeltaABC if a=(b-c)Sec theta then (2sqrt(bc))/(b-c)"Sin"(A)/(2)=

If a = (b-c) "sec" theta , then prove that tan theta = (2sqrt(bc))/(b-c) sin A/2 .

If a=(b+c)costheta, " then prove that" sintheta=(2sqrt(bc))/(b+c)cos((A)/(2))

In DeltaABC if a=(b-c)sectheta then (2sqrt(bc))/(b-c)sin(A/2)=

If sin theta = a/(b+c) then show that cos theta = (2sqrt(bc))/(b+c) cos ((A)/(2))

In any DeltaABC , prove that (i) tan""(B-C)/2=(b-c)/(b+c)cot""A/2 . (ii) If angleB=90^(@) , prove that tan(A/2)=sqrt(((b-c)/(b+c))) . (iii) If angleC=90^(@) , prove that tan((A−B)/2)/tan((A+B)/2)=(a-b)/(a+b) .
