WebApr 13, 2024 · The "unit circle" is a circle with a radius of one, centered at the origin of a Cartesian coordinate plane. Constructing triangles on the unit circle allows students to observe the trigonometric relationships of sine, cosine, and tangent of angles between zero and 360 degrees, or zero to 2pi radians, and every periodic coterminal angle greater ...
WebNov 23, 2024 · It may also be interesting that the Arabic word for tangent is "shadow" which is in use for more than 1000 years. In French, we use "tangente" as a noun ("la tangente d'une courbe", "la tangente d'un angle"). As an adjective, "tangent" and "tangente" are used, depending on the gender of the noun they characterize.
