Explicit

-- Graphic object: explicit (<fcn>,<var>,<minval>,<maxval>) -- Graphic object: explicit (<fcn>,<var1>,<minval1>,<maxval1>,<var2>,<minval2>,<maxval2>) Draws explicit functions in 2D and 3D.

2D

load(draw);
Po:[-4,-3];
P:[3,5];
m:(P[2]-Po[2])/(P[1]-Po[1]);
b:P[2]-m*P[1];
draw2d(explicit(m*x+b,x,-5,-4))

explicit(<fcn>,<var>,<minval>,<maxval>) plots explicit function <fcn>, with variable <var> taking values from <minval> to <maxval>.

This object is affected by the following graphic options: nticks, adapt_depth, line_width, line_type, key, filled_func, fill_color and color.

Example:

          (%i1) load(draw)$
          (%i2) draw2d(line_width = 3,
                       color      = blue,
                       explicit(x^2,x,-3,3) )$
          (%i3) draw2d(fill_color  = brown,
                       filled_func = true,
                       explicit(x^2,x,-3,3) )$

3D

explicit(<fcn>,<var1>,<minval1>,<maxval1>,<var2>,<minval2>,<maxval2>) plots explicit function <fcn>, with variable <var1> taking values from <minval1> to <maxval1> and variable <var2> taking values from <minval2> to <maxval2>.

This object is affected by the following graphic options: xu_grid, yv_grid, line_type, line_width, key, enhanced3d, and color.

Example:

          (%i1) load(draw)$
          (%i2) draw3d(key   = "Gauss",
                       color = "#a02c00",
                       explicit(20*exp(-x^2-y^2)-10,x,-3,3,y,-3,3),
                       yv_grid     = 10,
                       color = blue,
                       key   = "Plane",
                       explicit(x+y,x,-5,5,y,-5,5),
                       surface_hide = true)$

See also filled_func for filled functions.

There are also some inexact matches for explicit. Try ?? explicit to see them.
