What will I learn?

This course provides a quick and practical way to master angles, the unit circle, and the behaviour of sine and cosine functions. You will confidently convert between degrees and radians, identify key angles, apply reference angles, and use sign rules across all quadrants. Develop skills to model periodic motion accurately, graph functions with transformations, and verify solutions using systematic step-by-step approaches.
