In this course, we would continue to work on examples of basic trig from the ones we have seen in basic trigonometry. Read through all our notes before attempting these basic trig questions as they test on the concepts learnt on this trigonometry help website.
Examples of Basic Trig
a) Find the general solution of .
For this basic trig question, we have to consider the cases when n is an even or odd number.
Case 1: n=2k, Z
Case 2 : n= 2k+1 , Z
Solving Basic Trig Equations involving factor formula
Looking at the basic trig question , we realize that we have to split the complex trigonometry functions. Before we do that, we multiply the equation by 2 so that it fits the form
2cosAcosB = cos(A+B) +cos(A-B)
