Illustration of a unit circle (circle with a radius of 1) superimposed on the coordinate plane with the x- and y-axes indicated. The circle is marked and labeled in both radians and degrees at all quadrantal angles and angles that have reference angles of 30°, 45°, and 60°. At each angle, the coordinates are given. These coordinates can be used to find the six trigonometric values/ratios. The x-coordinate is the value of cosine at the given angle and the y-coordinate is the value of sine…

What is Circular Function? A Circular function can be defined in terms of an arc length and the coordinates of the terminal point of the arc on the unit circle. In this topic, we'll focus on studying its 3 basic Circular Functions which are Sine (Sin), Cosine (Cos), and Tangent (Tan) functions, and their Reciprocal Functions which are Cosecant (Csc), Secant (Sec), and Cotangent (Cot) functions.This is the image of the Unit Circle with angles in degree, radian measure, and their corresponding…

See description below. In mathematics, a unit circle is a circle with a radius of one. In trigonometry, 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 point of the unit circle is that it makes other parts of the mathematics easier and neater. For instance, in the unit circle, for any angle θ, the trig values for sine and cosine are clearly nothing more than sin(θ) = y and cos(θ) = x. ... Certain angles…

Math~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Our math department is divided. Some like teaching the trig ratios with the Unit Circle, some don't. Since I hate conflict, I teach both methods--one where students will draw a triangle in a quadrant and use what they know about 30-60-90 or 45-45-90 triangles to solve, and one where they learn the first quadrant of the unit circle and then reflect into other quadrants to get the answer. For years, I have assigned a unit circle project, where…
