Many times throughout a Calculus AP class trigonometric functions are used to study continuous functions, discontinuous functions, and inverse functions.   Therefore it is important that a student beginning their study of Calculus have an excellent grasp of all trigonometric functions.  The following pages will help you review the basic trigonometry you should remember. 

 
The first activity will instruct you how to fold a unit circle (Section 13).  Knowing the radian measure on this unit circle and the ordered pairs associated with each measure is extremely important.  Make sure you take time to memorize these ordered pairs.

The second section will review the basic trigonometric functions and converting between radians and degree measure. (Section 14)

 

The third section will review the key trigonometric identities (Section 15) which are often used in the integration or anti-derivative section of the Calculus course.

 
In the fourth section students can review their knowledge of the graphs associated with the six basic trigonometric functions. (Section 16)

 

 

This trigonometry section connects transformations to graphing trigonometric functions. (Section 17)  This means you will start with the basic trigonometric function and through stretching, shrinking, and sliding create a new graph. 

 

This final section on inverse trigonometric functions  (Section 18) will connect ideas about inverse functions to the six trigonometric functions.   

 

Gottfried Wilhelm von Leibniz

One of Leibniz's great achievements in mathematics was his development of the binary system of arithmetic.
