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

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

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

If a= ( b-c) sec theta " then " tan theta =

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

If asin^(2)theta+bcos^(2)theta=c , then prove that tan^(2)theta=(c-b)/(a-c)

If asin^(2)theta+bcos^(2)theta=c , then prove that tan^(2)theta=(c-b)/(a-c)

If alpha, beta be the solutions of theta for the equation a tan theta + b sec theta = c then prove that tan(alpha+ beta) = 2ac/(a^(2)-c^(2)) .

If alpha and beta are distinct roots of the equation : a tan theta+b sec theta=c , prove that tan (alpha+ beta)= (2ac)/(a^2-c^2) .
