Hello all,

I searched around but couldn't find any info.

How can we transform one coordinate to another on classpad300 (cartesian,cylindrical,spherical..) ?

Thank you

Define cartocyl(x,y,z)={(x^2+y^2)^.5,tan(^-1)(y/x),z}
Define cyltocar(r,th,z)={r*cos(th),r*sin(th),z}

Define cartoshp(x,y,z)={(x^2+y^2+z^2)^.5,tan(^-1)(y/x),cos(^-1)(z/r)}
Define shptocar(r,th,ph)={r*cos(th)*sin(ph),r*sin(th)*sin(ph),r*cos(ph)}

For the god sake! :r-t-f-m:

For the functions: ToPol,ToCyl,ToRect... on the vector operations submenu..
Not to be hard.. but, why the people ask questions that could be solved reading a bit (5~6 pages) each chapter of the users guide??? . If you read, you get a solution, if you not.. you need to wait one or more days to know how to...
