A scientific look at Trigonometry

Trigonometry courses included in the national secondary school curriculum are no longer taught in many schools due to a lack of adequate materials. Concerned by this issue, we wanted to address this subject in order to provide teachers and learners with a flexible and coherent resource.In this manual, we have not covered all aspects of trigonometry, but have focused on finding specific values of trigonometric numbers for notable angles in the trigonometric circle and solving a few trigonometric equations.
