Can I simplify this down anymore? a (a+b) (a-b) / a^2 + 2ab + 2b^2

Andrew [12]

I don't believe you can. It would end up being 1/2 for all the terms so just leaving it as a fraction would be neater.

Find the area of the surface. the part of the hyperbolic paraboloid z = y2 â x2 that lies between the cylinders x2 + y2 = 4 and

lukranit [14]

$x=u\cos v,y=u\sin v\implies z=u^2\sin^2v-u^2\cos^2v=-u\cos2v$

$\mathbf s(u,v)=\langle u\cos v,u\sin v,-u\cos2v\rangle$

$\mathrm dS=\|\mathbf s_u\times\mathbf s_v\|=u\sqrt{1+4u^2}\,\mathrm du\,\mathrm dv$

$\displaystyle\iint_{\mathcal S}\mathrm dS=\int_{v=0}^{v=2\pi}\int_{u=2}^{u=5}u\sqrt{1+4u^2}\,\mathrm du\,\mathrm dv=\dfrac{(101^{3/2}-17^{3/2})\pi}6$

How many solutions does the nonlinear system of equations graphed below

just olya [345]

Answer:

d four

Step-by-step explanation:

How many solutions does the nonlinear system of equations graphed below have?

Look at the number of points where the graphs intersect each other...the points where the graphs of the functions cross each other are the solutions to the system.

Upon looking, you should see 4 points where the graphs intersect, so there are 4 solutions to the non-linear system of equations.
