A heart has only 1 line of symmetry. The one line is in the middle. I hope this helped.

A heart has one line of symmetry, right down the middle.

Identify the surface with the given vector equation. r(u, v) = 2 sin(u) i + 5 cos(u) j + v k, 0 ≤ v ≤ 5 plane hyperbolic parabol

olchik [2.2K]

Note that this just produces three parametric equations:

$x(u) = 2 \sin(u)$
$y(u) = 5 \cos(u)$
$z(v) = v$

In the $x-y$ plane, this is just he parametric equation for an ellipse (as a function of u). The z is simply a linear function.

The surface is then an ellipse extruded along the z-axis. We get a elliptic cylinder.

What is it??????????

Hey! :)

Some things to note: When you bring a exponent to the numerator, you make it negative.

When you put an exponent to another exponent, you multiply the exponents together.

$(\frac{3x^2y^5}{x^6y^2} )^4\\\frac{81x^8y^{20}}{x^{24}y^8}\\81x^8x^{-24}y^{20}y^{-8}\\\frac{81y^{12}}{x^{16}}$
