According to the paper, they can be illustrated using the trigonometric technique or by using polynomials (algebraic expressions composed of several variables and coefficients) of complex numbers.

Strategy 1: Convert everything to Sine and Cosine When faced with a complex trigonometric expression, your first move should be converting all functions to sine and cosine.
