Oct 5, 2017 · The idea is to plug in the values of $x$, $y$ and $z$ in $$z = \sqrt{x^2+y^2}.$$ Specifically, by using the given expressions, we get $$p \cos \phi = \sqrt{p^2\sin^2\phi \cos^2 \theta + p^2\sin^2\theta \sin^2 \phi}$$ $$p \cos\phi = \sqrt{p^2\sin^2 \phi \ (\sin^2 \theta + \cos^2 \theta)} $$ $$p \cos\phi = p \sin \phi$$ $$\cos \phi = \sin \phi ...
May 29, 2023 · To express the equation of the paraboloid z = x^2 + y^2 in spherical coordinates (ρ, Φ, θ), we need to convert the Cartesian coordinates (x, y, z) to spherical coordinates. In spherical coordinates, the conversion formulas are as follows: x = ρsin(Φ)cos(θ) y = ρsin(Φ)sin(θ) z = ρcos(Φ)

Nov 10, 2020 · In three-dimensional space R3 a point with rectangular coordinates (x, y, z) can be identified with cylindrical coordinates (r, θ, z) and vice versa. We can use these same conversion relationships, adding z as the vertical distance to the point from the (xy -plane as shown in 15.8.1.
Feb 16, 2015 · This is equation of a sphere, so you can write immediately that $$R^2=49,$$ since $x^2+y^2+z^2=R^2$. But you could get to this the way you started, simply by repeatedly using $\cos^2x+\sin^2x=1$ to simplify your final expression.
