Analytically show that the equation represents the given trigonometric identity statement on the right side. To get correct answer, you must type cos a as cos (a ). cos(y) (cos(y) - sec(y)) = - sin?(y) cos (y) - cos(y) 1 cos (y ) cos(y) cos(y) - cos(y) - - sin?(y) = - sin?(y) K - - sin?(y) -sin (y ) V = - sin?(y)
