Trigonometry

In this course, we will cover all you need to know about trigonometry in a right-angled triangle, obtuse and acute triangle, congruency and similarity test. This will form the foundation of your understanding of further trigonometry in the unit circle, graphs and other trigonometry identities in Additional Math. By the end of this course you would learn: Sin rule Cos rule Congruency and similarity triangle proof real-life application of trigonometry (angle of elevation/depression/pythagoras Theorem) https://www.facebook.com/learnwlishuang/
