    How Fast is the Distance Changing as a Particle Moves Along y=sqrt(x)?

    You're given the acceleration (3cm/s2) at the X-ordinates. Maybe you should be intergrating to find the velocity.

    Determining best method for volumes?

    Because one of the methods is easier than the other. In certain situations, the shell method is easier to do than the disk method. And we all know mathematicians are lazy. ;) Think about it this way: if you were to find the area of a cone (y = x) that revolved around the x-axis, you'ld use...

    Solving the Level Curves of T(x,y)

    Thanks guys! I'll have Complete The Square burned into my memory from now on.

    Determining best method for volumes?

    It depends on what axis they're revolving.

    Solving the Level Curves of T(x,y)

    Ok, I've been trying to work this out for a couple of hours now and I'm completely stumped. Not even Google was helping much. The question is: Find and Sketch the level curves of the scalar field T(x,y) = (x +y)/(x2 + y2) for T = -1, -0.5, 0, 0.5, 1[/size] I know that I should equate the...
