Search and find , solution and answer with Wolfram Alpha PART 2:

Wolfram|Alpha introduces a fundamentally new way to get knowledge and answers—
not by searching the web, but by doing dynamic computations based on a vast collection
of built-in data, algorithms, and methods.



PART 2 : Lets look at the mathematical searches and plotting

The following is not intended to be a handbook,
but only a listing of search examples


Plotting & Graphics
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 multiple functions
plot sin x, cos x, tan x
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

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

Number Lines

visualize a set of real numbers on a number line
number line 2, 3, 5, 7, 11, 13
