## NewMapleGraph...

Maple
It's me again, got another problem i have another hyperbolic paraboloid equation 3*x^2-5*y^2=z and it's conic sections at xy(z=0), xz(y=0), and yz(x=0) plane 3x^2-5y^2=0 3x^2-z=0 5y^2+z=0 but i have problems converting those conic equations into parametric equation, so it can be plotted using the spacecurve command Can someone help??

## MapleGraph...

Maple
I am stock on this my prof gave me an equation to draw on maple 16x^2=y^2+4z^2 and this is the code i keyed in restart: with(plots): > p1:=implicitplot3d(16*x^2=y^2+4*z^2,x=-100..100,y=-100..100,z=-100..100,numpoints=2000,style=wireframe): > display(p1); and the graph suppose to be a cone rotating around the x-axis but i don't know wut i did wrong, i just couldn't get the graph look like a cone, instead, it looks like a hyperboloid of two sheets, and the sheets are very close to each other Can someone help?? Thx

## Quadric Surface graph and its trace...

Maple
The equation of a sphere is x^2+y^2+z^2=1, and its traces are x^2+y^2=1-k^2 z=k x^2+z^2=1-k^2 y=k y^2+z^2=1-k^2 x=k can somone help me how to graph the traces using spacecurve command so the traces matches the sphere? thx!!

## parameterize equation...

Can someone help me with this?? i have x^2+y^2+z^2=1 and y=z and now i find the equation of their intersection which is x^2+2z^2=1 but then i have problem parameterize it since i let x=cost, y=sint, and since y=z, then z=sint but if i plug it back to the equation (cost)^2+2(sint)^2=1, which is not correct, can someone help me wut to set for z?? Thx

## Quadric Surfaces and Space Curves...

Maple
Can someone help me with parameterizing equations and plot it into maple to show the graph For example x^2 + y^2 + z^2=1 How do i parameterize it for each of the traces and turn the equation into a space curve in R^3? Also, how do i plot the surface and the curves together on the same plot, using a grey wire frame for the surface, a black line for the x=k trace, a blue line for the y=k trace and a red line for the z=k trace? Thx
