All DP mathematics courses serve to accommodate the diverse range of needs, interests and abilities of students, and to fulfill the requirements of various university and career aspirations. The aims of these courses are to enable students to: develop mathematical knowledge, concepts, principles, logical, critical and creative thinking, employ and refine their powers of abstraction and generalization. Students are also encouraged to appreciate the international dimensions of mathematics and the multiplicity of its cultural and historical perspectives.

Trigonometry is the branch of mathematics that deals with relations of sides and angles of triangles and with the relevant functions of any angles as a whole. This is further emphasized as this chapter will look at the following in great detail: Reciprocal trigonometric functions, Inverse trigonometric functions, Algebra with trigonometric functions, Double angle identities and Compound angle identities. Reciprocal trigonometric functions deal with reciprocal functions of sin x, cos x, and tan x. Inverse trigonometric functions are the inverse of reciprocal trigonometric functions – sin- 1, cos-1, and tan- 1 these defined as arcsine, arccosine, and arctangent respectively. Algebra with trigonometric functions involves comparing algebraic tribometer expressions and simplifying them. It also delves into knowing the trigonometry identities such as The Pythagorean identity. Double angle and compound angle identities are further progressions of algebra with trigonometric functions that involve investigation, factorization and proofing while using the unit circle.
