Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
-- Graphic object: explicit (<fcn>,<var>,<minval>,<maxval>) -- Graphic object: explicit (<fcn>,<var1>,<minval1>,<maxval1>,<var2>,<minval2>,<maxval2>) Draws explicit functions in 2D and 3D.

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.
