Finding the area enclosed by curves in polar form Homework Statement a) Find the area enclosed by the curve r=2+3cos(\theta). b) Find the area enclosed by the curve (x^2+y^2)^3=y^4 (after converting to polar form) Homework Equations The general equation for the area of a sector...
Its equation in rectangular coordinates is (x2 + y2 –2ax)2 = 4a(x2 + y2); in polar coordinates it is ρ = 2a(1 + cos ϕ). (b) Conchoid of Nicomedes (Figure 2, b), a curve generated by increasing or decreasing the radius-vector of each point of a given line by the ...
Symmetry in Polar CoordinatesWhen studying symmetry of functions in rectangular coordinates (i.e., in the form y=f(x)y=f(x)), we talk about symmetry with respect to the y-axis and symmetry with respect to the origin. In particular, if f(−x)=f(x)f(−x)=f(x) for all xx ...

As mentioned above,B^1\times \mathbb {R}is space form of Sasakian manifold of negative curvature, while the CR 3-sphereS^3and the Heisenberg groupH_1are, respectively, space forms of Sasakian manifold of positive and zero curvature. In view of the results about the differential geometry of...
Points of Intersection of Polar Curves Given two functions in the polar form, we can use algebra and trigonometry to find the points of intersection of the two curves in the XY plane. This is done as follows. Given two polar functions r=f(θ)andr=g(θ), we fin...
Homework Statement (a) Let \alpha:I=[a,b]→R^2 be a differentiable curve. Assume the parametrization is arc length. Show that for s_{1},s_{2}\in I, |\alpha(s_{1})-\alpha(s_{2})|≤|s_{1}-s_{2}| holds. (b) Use the previous part to show that given \epsilon >0 the...
