This self checking worksheet is a must for every beginning trig students!! It features all the reciprocal functions (secant, cosecant, cotangent), even and odd identities (such as cos(-x)), and co-function values (such as sin(pi/2 - x)) which are all mixed together just begging to be simplified. Since most students are not good with fractions, this worksheet is usually a nightmare for them. It will help them work through those bad time with a touch of humor at the end. Upon completion, the students will reveal the author to several not-so-well known books.
