Unit Circle - Overview

In mathematics, the unit circle is a circle with a radius of one. Frequently, especially in trigonometry and geometry, the unit circle is the circle of radius one centered at the origin (0,0) in the Cartesian coordinate system in the Euclidean plane. The unit circle is often denoted S1; the generalization to higher dimensions is the unit sphere.

Angles And Measure - Overview

In mathematics, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane. Angles are also formed by the intersection of two planes in Euclidean and other spaces. Angles formed by the intersection of two curves in a plane are defined as the angle determined by the tangent rays at the point of intersection. Similar statements hold in space, for example, the spherical angle formed by two great circles on a sphere is the dihedral angle between the planes determined by the great circles. Angle is also used to designate the measure of an angle or of a rotation.

Right Triangle Trig - Overview

In mathematics, trigonometry is the study of the relationships between the sides and the angles of triangles. Trigonometry is used in solving problems in similar triangles, right triangles, triangles presented by their co-ordinates, spherical triangles, and triangles on elliptical arcs. Trigonometry is also used for computing the lengths of the sides of a triangle given one side and the angle opposite that side. Trigonometry is used in navigation, engineering, and physics. Trigonometry is the study of triangles, specifically the relationships between the sides and the angles of triangles. The area of a triangle is half the base times the height. The trigonometry functions are used to relate the sides and the angles of a triangle.

Graphing Trig Functions - Overview

In mathematics, the sine, cosine, and tangent functions — or, more generally, trigonometric functions — are functions of an angle. The trigonometric functions are commonly used in the study of triangles and modeling periodic phenomena, among many other uses. The most familiar trigonometric functions are the sine, cosine, and tangent. All of them have the value 0 when the argument (angle) is 0. The sine and cosine functions are periodic, with period 2?, while the tangent function is not periodic. The tangent function is, however, continuous, which means that it has a derivative at every point.
