Plotting & Graphics

Functions

plot a function of one variable
plot x^3 - 6x^2 + 4x + 12 graph sin t + cos (sqrt(3)t) plot 4/(9*x^(1/4))
specify an explicit range for the variable
plot e^x from x=0 to 10
plot a function where it is real-valued
real plot -(sqrt(25-y^2))
plot a special function
plot Ai(x)
plot several functions
plot sin x, cos x, tan x plot x e^-x, x^2 e^-x, x=0 to 8
plot a function on a logarithmic scale
log plot e^x-x
plot on a log-linear scale
log-linear plot x^2 log x, x=1 to 10

3D Plots

plot a function of two variables
plot sin x cos y
specify explicit ranges for the variables
plot x^2 y^3, x=-1..1, y=0..3

Equations

plot the solution to an equation in two variables
plot 3x^2-2xy+y^2=1
plot a quadric surface
plot x^2 - 3y^2 - z^2 = 1

Inequalities

plot the region satisfying an inequality in two variables
plot |x|^3+|y|^3<1
plot a region satisfying multiple inequalities
plot x^2+y^2<1 and y>x

Polar Plots

draw a polar plot
polar plot r=1+cos theta
specify a range for the variable theta
polar plot r=theta, theta=0 to 8 pi

Parametric Plots

draw a parametric plot
parametric plot (cos^3 t, sin^3 t)
specify a range for the parameter
parametric plot (sin 10t, sin 8t), t=0..2pi
