After you solve a trigonometric equation, you can use this program to find several values of the angle using tan( and cos( as well as sin(. This program will give you 4 values in positive degrees for the angle and those values in radians. This is a must-have for any math student in any math level-it has over 30 features if you count everything.ĭon't you hate it when you type sin(angle)=something and you only get 1 value for the angle. Some of the features are the quadratic solver, the radian/degree converter, and area and volume (includes 10 different geometric shapes).
Math OS is a math program that has (basically) everything you need.

Fill-in version (without Tangent Values) Fill-in version (includes Tangent values) Fill-in version with some guidance (includes Tangent values) I also stress the fact that a unit circle has a radius of one, so that quadrantal angles values are easily memorized. This is quite helpful when learning about coterminal and reference angles. I like to place this sheet in a page protector to use as a dry erase tool. This trick is especially valuable for students who have a difficult time committing the trig facts to memory even after drawing countless number of special right triangles. Two versions of the unit circle are included, one with and without hand trick notes.Ī separate page contains detailed notes on the hand trick that I like to use for memorizing the unit circle trigonometry facts. I have purposely placed the tangent values only in the first quadrant to emphasize the ratios. I have included a symbolic key for the range of inverse functions, alongs with information on Tangent and reciprocal identities.Ĭolor coding emphasizes the special right triangle ratios.
I have tweaked it over 10 years and finally created the perfect teaching tool to fit on one page! This is my version of the unit circle on steroids. Unit Circle Trigonometry Cheat Sheet with hand trick memorizing details.
