As trigonometry consists largely of formulae and applications thereof, the complete elementary textbook on Plane Trigonometry in Classic Text Series is compiled with a list of principle formulae, suitable for schools, higher studies. The book has endeavoured to present, as simply as possible, the modern treatment of complex quantities, large number of examples, and a section of questions to be solved by students.
Worked examples and exercises with answers are also presented to identify gaps in understanding.
