In this chapter, the equation (6.1) where a, b and c are real parameters, a 2 + b 2 ≠ 0, will be considered. A problem-solving technique based on reducing trigonometric Eq. (6.1) to the system of simultaneous algebraic equations, (6.2–6.3) will be explored. In the digital era, trigonometry curriculum can be made enjoyable provided that computer applications are used to illuminate mathematical ideas. Towards this end, the chapter will emphasize the importance of technology for the teachers’ understanding of connections that exist between trigonometry and geometry.
