SOLUTION: Determine If The Graph Is Symmetric About The X

For x-axis symmetry in a polar graph, it means we are replacing the angle x with the angle (360-x). So the question is whether cos (360-x) is equal to cos (x). The formula for the cosine of the difference of two angles tells us that it is: So the graph of r = 5cos (3x) has symmetry about the x-axis.Graph B: This graph is symmetric about the axes; that is, it is symmetric about the lines x = 0 (the y-axis) and y = 0 (the x-axis). It is also symmetric about the origin. Since there exist vertical lines (such as the line x = 2) which will cross this graph twice, what it shows is not a function.In this section we introduce the idea of symmetry. We discuss symmetry about the x-axis, y-axis and the origin and we give methods for determining what, if any symmetry, a graph will have without having to actually graph the function.Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = -5 - 5 cos θ . Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 2 cos 5θ . Find all polar coordinates of point P = (6, 31°) Determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°r = 1 + 2 sin x . 3) Determine if the graph of the following equation is symmetric about the x-axis, the y-axis, or the origin. r = -3 + 5 cos x . 4) Express the complex number 6 in trigonometric form.

Algebra - Symmetry

Answer. Answer:It is symmetric about x- axisThe graph is not symmetric along the y - axisIt is not symmetric about the originStep-by-step explanation:We can easily know the solution to your problem by graphing the equationr(θ) = 2*cos (5*θ)Please, see attached imageThe graph is symmetric about the x axis ifr(θ) = r(-θ)r(θ) = 2*cos (5*θ) = 2*cos (-5*θ) = r(-θ)Since the cosine is anQuestion: Question 10(Multiple Choice Worth 5 Points) Determine If The Graph Is Symmetric About The X-axis, The Y-axis, Or The Origin. R= 4 + 5 Cos θ Origin Only O Y-axis Only No Symmetry X-axis Onlysymmetrical about y-axis if f(θ) = f(pi - θ) symmetrical about the origin if f(θ) = f(pi+θ) has no symmetry if none of the conditions above holds. So you have to check each one separately. But I will tell you right off the bat that it is symmetrical only about the x-axis. since r = -5 - 5cos(-θ) = -5 - 5cos(θ)Answer to 1.Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 4 - 3 sin CHOICES: A)Origin only B)x-axis only C)y-axis onlyDetermine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 8 cos 3θ?
