10 Secret Trig Functions  A diagram with a unit circle and more trig functions than you can shake a stick at. (It's well known that you can shake a stick at a maximum of 8 trig functions.) The familiar sine, cosine, and tangent are in red, blue, and, well, tan, respectively. The versine is in green next to the cosine, and the exsecant is in pink to the right of the versine. Excosecant and coversine are also in the image. Not pictured: vercosine, covercosine, and haver-anything.

Todas las funciones trigonométricas del ángulo θ se puede construir geométricamente en términos de una unidad de círculo con centro en O.

In this worksheet, students must convert a non-standard angle (not between 0 and 360 degrees) to an angle in standard form and then use the unit circle to evaluate its sin, cos or tan.  This activity requires NO PREP. Student and teacher documents included.  Common Core Standards HSF-TF.A.1, HSF-TF.A.2

Illustration of a unit circle (circle with a radius of 1) superimposed on the coordinate plane. The circle is divided into four quadrants by the x- and y- axes. The circle can be labeled and used to find the six trigonometric values (sin, cos, tan, cot, sec, csc, cot) at each of the quadrantal angles.

New for 2017: Spotlight on Write-On/Wipe-Off Unit Circle Mats  http://ift.tt/2m28Nkz  A great way for students to practice evaluating trig functions each mat features a unit circle showing all segments on one side and a circle with just xy segments on the other side. Students can fill in radians sin cos tan using dry-erase markers (not included). Mats measure 9 x 12 and are made of tough flexible plastic. #highschoolteacher #mathteacher #didax #teachers #education #pinterest #teachergram
