    Just as points in 2 space can be placed in one to one correspondence with pairs of real numbers using two perpendicular coordinate lines, so points in 3 space can be placed in one to one correspondence with triples of real numbers by using three mutually perpendicular coordinate line called x-axis, the y-axis and z-axis. Am i right?

    Well you can just say it's a tuple (x,y,z) where x, y and z are real numbers. If you want to know more about it and particularly how to manipulate objects in it try multivariable calculus. It will take you from vectors, and planes in n-space to evaluating line and surface integrals. It deals mostly with 3-space

    The cartesian coordinate system usually used in 3-space is a right handed triple. But you often have other basis

    The set of points with three positive coordinates forms the first octant. And why is it that the remaining octant have no standard numbering?

    What do you mean standard numbering. It's just like with quadrants in the x-y plane.

    sa rectangular system, ang first component ay distance from the x-axis, and second component ay distance sa y-axis, at ang third component ay distance sa z-axis. so, "rectangles" and maform sa bawat plane.

    Yes. can you do it for me? Am i right that the standard equation of the sphere is the same as the standard equation of a circle in 2 space, but with an additional term to account for the third coordinate?

    yes, you are right. it's \[(x-x_0)^2 + (y-y_0)^2 + (z-z_0)^2 = r^2\] a sphere with radius r>0 and center at ((x0, y0, z0)

    if k>0, then the graph of this equation is a sphere with center (x0,y0,z0) and radius sqrt of k . Am i right?

    if you are refering to the equation (x-xo)^2 + (y-yo)^2 + (z-zo)^2 = k > 0, then yes, you are right, the radius is r=sqrt(k)

    Yes. then if k=0, then the sphere has a radius zero, so that graph is the single point (x0,y0,z0) ? Am i also right ?

    if you need a software to view curves in space and surfaces, you may want to use this software free from microsoft. 32-bit windows application: http://download.microsoft.com/download/F/7/6/F76E0187-07B5-4958-B3FF-2E5ACD53B637/MSetup_x86.exe 64-bit-application: http://download.microsoft.com/download/F/7/6/F76E0187-07B5-4958-B3FF-2E5ACD53B637/MSetup_x64.exe

    So, then if \[k <0\], the equation is not satisfied by any values of x,y and z (why?) so it has no graph. Right sirm3d?

    again, the answer is yes. it will be the curve in the plane involving the two variables, retraced in each plane parallel to the starting plane.
