Spherical Coordinates - Definition, Conversions, Examples

WebJan 22, 2024 · Spherical coordinates are useful in analyzing systems that have some degree of symmetry about a point, such as the volume of the space inside a domed stadium or wind speeds in a planet’s atmosphere. A sphere that has Cartesian equation … WebThe answer is: x2 + y2 +z2 + ax +by +cz + d = 0, This is because the sphere is the locus of all points P (x,y,z) in the space whose distance from C(xc,yc,zc) is equal to r. So we can use the formula of distance from P to C, that says: √(x −xc)2 + (y −yc)2 + (z − zc)2 = r and so: (x −xc)2 + (y − yc)2 +(z −zc)2 = r2, debit card for disability benefits
