Показать описание
Cape Pure Mathematics Unit 1
Module 2 Trigonometry
Angle sum & Double Angle Formulas
This video covers foundational aspects to a major topic in the trigonometry section, if you understand these expansions as well as everything in past videos you will have no issues on the trigonometry section of the exam. However these things come with practice, so ensure to actually try the questions while I work them and use the video to see if you are wrong or right.
