sine of an angle is the y value of the radius when it is at that angle, so it is even less than sin(pi/6), so we know that at least. Hence, cos(180o − θ) = cos180ocosθ +sin180osinθ. Sin (180) × Cos (x) - Sin (x) × Cos (180) = Sin (x) Posteriormente, reemplazamos las razones trigonométricas por su respectivo equivalente. From the expression (2), Using complementary angle identity, Sin A = cos (90°- A) we can write the above expression as: Sin 180°= cos (90° – 180°) Sin 180°= cos (-90°) Now, use opposite angle identity cos(-A) = cos A. Khi đó ta có: sin( 90° – α ) = cosα; cos( 90° – α ) = sinα. tan 0°= 0/1 = 0. I myself think that the idea of cos 180 is equal to 1 is : cos 180 = cos (180 - 0) cos 180 = -cos 0 "which is cos (180-a) =- cos a" cos 180 =- 1. Sine Value Table. This is probably a typo on his part; it doesn't affect the proof at all. tan 180° = sin 180°/cos 180° = 0/ (-1) = 0.
