If `alpha, beta` are the eccentric angles of the extermities of a focal chord of an ellipse, then eccentricity of the ellipse is

The eccentricity of the ellipse

If alpha and beta are the eccentric angles of the extremities of a focal chord of an ellipse, then prove that the eccentricity of the ellipse is (sinalpha+sinbeta)/("sin"(alpha+beta))

If alpha and beta are the eccentric angles of the extremities of a focal chord of an ellipse, then prove that the eccentricity of the ellipse is (sinalpha+sinbeta)/("sin"(alpha+beta))

If alpha and beta are the eccentric angles of the extremities of a focal chord of an ellipse,then prove that the eccentricity of the ellipse is (sin alpha+sin beta)/(sin(alpha+beta))

If alphaa n dbeta are the eccentric angles of the extremities of a focal chord of an ellipse, then prove that the eccentricity of the ellipse is (sinalpha+sinbeta)/("sin"(alpha+beta))

Define eccentricity of an ellipse

IF alpha,beta are the eccentric angles of the extremities of a focal chord of the ellipse x^2/a^2+y^2/b^2=1 . Then show that e cos""(alpha+beta)/2=cos""(alpha-beta)/2

If alpha,beta are the eccentric angles of the extremities of a focal chord of the ellipse x^(2)/16 + y^(2)/9 = 1 , then tan (alpha/2) tan(beta/2) =

If the theta and varphi be the eccentric angles of the two ends of a focal chord of an ellipse then show that pm e "cos" (theta + varphi)/(2) = "cos" (theta- varphi)/(2)*
