WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. WebSolution: As we know that (1 - cos x) = 2sin 2 (x/2) and sin x = 2sin (x/2).cos (x/2) (1 - cos x) = 2sin 2 (x/2) ---- (1) sin x = 2sin (x/2).cos (x/2) ---- (2) (1 - cos x) / sinx = 2sin 2 (x/2) / 2sin (x/2).cos (x/2) [From (1) and (2)] On taking 2sin (x/2) common and cancelling, we get (1 - cos x) / sinx = sin (x/2) / cos (x/2)
WebThis periodicity constant is different for different trigonometric identities. tan 45° = tan 225° but this is true for cos 45° and cos 225°. Refer to the above trigonometry table to verify the values. Cofunction Identities (in Degrees) The co-function or periodic identities can also be represented in degrees as: sin (90°−x) = cos x
Notice how a "co-(something)" trig ratio is always the reciprocal of some "non-co" ratio. You can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine.
