WebIn a modern presentation of trigonometry, the sine and cosine of an angle a are the y - and x -coordinates of a point on the unit circle, the point being the intersection of the unit circle and one side of the angle a; the other side of the angle is the positive x -axis.

WebWhen is it possible to make a right-angled triangle? In this interactivity, the points are equally spaced around a circle. Imagine that they are not. Can you explain the conditions … WebWe normally label angles in two main ways: 1 By giving the angle a ‘name’ which is normally a lower case letter such as a, x or y or the greek letter ϴ (theta). 2 By referring to the angle as the three letters that define the angle. The middle letter refers to the vertex at which the angle is e.g. see the diagram for the angle we call ABC: department of corrections farmington mo
