Consider the curver=⟨cost,5sint,2cost⟩.r→is a sphere. Find the center and the radius of the circle. Sphere in polar form In this question, polar form of circle is given we need to convert in coodina...
polar-cap modelfree electron emissionThe effect of the radius of the tube of open magnetic-field lines on the gamma-ray curvature radiation from the polar regions of a radio pulsar with a non-dipolar magnetic field is analyzed. The pulsar is considered in a polar-cap model with free ...
∬D(x2+y2)dA where D is the circular disk of radius 1 centered at the origin. Double Integrals A double integral of a function of two variables, f(x,y) over a region in plane, D is given as ∬Df(x,y)dA. To solve a double int...
