unit circle in mathematics a unit circle is a circle with unit radius frequently especially 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 unit circle breakdown math is fun the "unit circle" is a circle with a radius of 1 being so simple it is a great way to learn and talk about lengths and angles the center is put on a graph where the x axis and y axis cross so we this neat arrangement here have a try move the mouse around to see how different angles in trigonometry review with the unit circle all the trig for your own reference 1 radian 57 30 ≈ d a radian is defined by the radius of a circle if you measure off the radius of the circle then take angles and the unit circle – she loves math degrees radians and co terminal angles degrees again since there are 360° in a circle do you see why it makes sense that an angle that is formed by rotating the terminal side 360° actually coincides with itself – it’s the same angle the unit circle cool math if you don t know off the top of your head then you need this section these critters are going to pop up over and over again in calculus the unit circle is a great way to remember your trig values trigonometry the unit circle the unit circle since the trigonometric ratios do not depend on the size of the triangle you can always use a right angled triangle where the hypotenuse has length one circle group in mathematics the circle group denoted by t is the multiplicative group of all plex numbers with absolute value 1 that is the unit circle in the plex plane or simply the unit plex numbers = ∈ origins of the names of trigonometric functions introduction originally all six trigonometric values were defined by the lengths of the sides of the triangles the chord and the secant as shown in the following unit circle diagram the unit circle cool math this precalculus review calculus preview lesson reviews the unit circle and basic trigonometric trig identities and gives great tips on how to remember everything sine history of trigonometry and the unit circle tangen casey trenkamp why question 40 why is the unit circle important where did trigonometry originate from how were the cosine and tangent functions invented
