Trigonometric integration without trigonometric functions
Teaching Mathematics and its Applications, 2016Teaching techniques of integration can be tedious and often uninspired. We present an obvious but underutilized approach for finding antiderivatives of various trigonometric functions using the complex exponential representation of the sine and cosine. The purpose goes beyond providing students an alternative approach to trigonometric integrals.

In this chapter, we will define the Trigonometric Circle and extend the concept of angle discussed in Sec. 10.6 to angles whose measurement can be any real number [rather than angles whose measurement have to be between “0” (zero) and “2 π” (Rfullturn)].

Problems: Trigonometric and Inverse Trigonometric Functions
2021In this chapter, the basic and advanced problems of trigonometric and inverse trigonometric functions are presented. To help students study the chapter in the most efficient way, the problems are categorized in different levels based on their difficulty levels (easy, normal, and hard) and calculation amounts (small, normal, and large).

The Mathematics Teacher, 1950
In this article we shall indicate many different methods by which the sine and cosine functions may be defined. (From these the other four functions may be obtained by their usual definitions in terms of the sine and cosine functions, viz., cot θ = cos θ/sin θ.) In the course of the discussion we shall consider the trigonometric functions from various ...

The Mathematics Teacher, 1958
Herein is presented a definition of trigonometric functions not usually found in elementary texts. Continuing in the same unusual way, properties of these functions are derived in a manner simple enough to use in an early calculus course.
