Sketching sin graphs
WebbSketch the graph of r = 2 + 2cosθ. Solution First, testing the equation for symmetry, we find that the graph of this equation will be symmetric about the polar axis. Next, we find the zeros and maximums. Setting r = 0, we have θ = π + 2kπ. The zero of the equation is located at (0, π). The graph passes through this point. WebbTo sketch the trigonometry graphs of the functions – Sine, Cosine and Tangent, we need to know the period, phase, amplitude, maximum and minimum turning points. These …
