WebCosine. Cosine, written as cos⁡(θ), is one of the six fundamental trigonometric functions.. Cosine definitions. There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles and in terms of the unit circle.The right-angled triangle definition of trigonometric functions is most often how they are introduced, followed by … WebIn the third quadrant, all x and y values will be negative, so all sine and cosine values will be negative. Tangent will be positive because a negative divided by a negative is positive.) The final quadrant is the fourth quadrant, and there, all x values are positive, but all y values are negative, so sine will be negative, cosine will be ...
