Countdown to Exams - Day 44 - Trigonometry functions

Countdown to Exams - Day 44 - Trigonometry functions

We move onto Trigonometry for day 44. We will focus on the trig functions of Sine, Cosine and Tangent. For your exam, you will be required to know specific angle values of Sin, Cos and Tan and these can be seen in the tables. You will also have to know how to use the functions in order to calculate missing angles and side lengths in right angled triangles. Before you start any trigonometry problem, it will be crucial to label your right angled triangle with Opposite, Adjacent and Hypotenuse accuratley. This will then help to decide which of the three trigonometry functions to use.
