Need HELP!!! For all, I’m truly confused

irina1246 [14]

Step-by-step explanation:

You need to know some geometry rules.

For example:

Angle sum of a triangle is equal to 180 degrees.

Straight line is equal to 180 degrees.

Other rules I have attached.

If you have any confusion over these I will be happy to answer your questions.

Can some please show work and the answer to this problem

solmaris [256]

1. $\lim_{x\to+-\infty}x^3-4x^2+x\\(+-\infty)^3-4(+-\infty)^2+(+-\infty)\\\infty,-\infty$

2. $\lim_{x \to +-\infty} x^4-4x^3+2x+8\\(+-\infty)^4-4(+-\infty)^3+2(+-\infty)+8\\\infty$

3. $\lim_{x \to +-\infty} -2x^3-4x^2+9\\-2(+-\infty)^3-4(+-\infty)^2+9\\-\infty,\infty$

4. $\lim_{x \to +-\infty} -x^4+9x^3+x^2+8x+2\\-(+-\infty)^4+9(+-\infty)^3+(+-\infty)^2+8(+-\infty)+2\\-\infty$

4 is the only function that decreases as it approaches both infinities.

Compute the differential of surface area for the surface S described by the given parametrization.

AysviL [449]

With $S$ parameterized by

$\vec r(u,v)=\langle e^u\cos v,e^u\sin v,uv\rangle$

the surface element $\mathrm dS$ is

$\mathrm dS=\left\|\dfrac{\partial\vec r}{\partial u}\times\dfrac{\partial\vec r}{\partial v}\right\|\,\mathrm du\,\mathrm dv$

We have

$\dfrac{\partial\vec r}{\partial u}=\langle e^u\cos v,e^u\sin v,v\rangle$

$\dfrac{\partial\vec r}{\partial v}=\langle -e^u\sin v,e^u\cos v,u\rangle$

with cross product

$\dfrac{\partial\vec r}{\partial u}\times\dfrac{\partial\vec r}{\partial v}=\langle ue^u\sin v-ve^u\cos v,-ve^u\sin v-ue^u\cos v,e^{2u}\cos^2v+e^{2u}\sin^2v\rangle$

$\dfrac{\partial\vec r}{\partial u}\times\dfrac{\partial\vec r}{\partial v}=\langle e^u(u\sin v-v\cos v),-e^u(v\sin v+u\cos v),e^{2u}\rangle$

with magnitude

$\left\|\dfrac{\partial\vec r}{\partial u}\times\dfrac{\partial\vec r}{\partial v}\right\|=\sqrt{e^{2u}(u\sin v-v\cos v)^2+e^{2u}(v\sin v+u\cos v)^2+e^{4u}}$

$\left\|\dfrac{\partial\vec r}{\partial u}\times\dfrac{\partial\vec r}{\partial v}\right\|=e^u\sqrt{u^2+v^2+e^{2u}}$

So we have

$\mathrm dS=\boxed{e^u\sqrt{u^2+v^2+e^{2u}}\,\mathrm du\,\mathrm dv}$
