Cosine of 100 degrees
WebSince the cosine function is a periodic function, we can represent cos 180° as, cos 180 degrees = cos (180° + n × 360°), n ∈ Z. ⇒ cos 180° = cos 540° = cos 900°, and so on. Note: Since, cosine is an even function, the value of cos (-180°) = cos (180°). Methods to Find Value of Cos 180 Degrees The value of cos 180° is given as -1. WebThe Sine function ( sin (x) ) The sine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the opposite side to the longest side of the triangle. In the illustration below, sin (α) = a/c and sin (β) = b/c. From cos (α) = a/c follows that the sine of any angle ...

WebThe law of cosines allows us to find angle (or side length) measurements for triangles other than right triangles. The third side in the example given would ONLY = 15 if the angle between the two sides was 90 degrees. In the example in the video, the angle between the two sides is NOT 90 degrees; it's 87. As such, that opposite side length isn ...
