Using pari how do we plot graphs: For example would be glad to receive step by step instructions to plot

2^n+ 7.
tks

step 1: open pari/gp
step 2: write at the command prompt: plot(x=-10,10,2^x+7) and press enter

Code:

(12:40:06) gp > ?plot
plot(X=a,b,expr,{Ymin},{Ymax}): crude plot of expression expr, X goes from a to b, with Y ranging from Ymin to Ymax. If Ymin (resp. Ymax) is not
given, the minima (resp. the maxima) of the expression is used instead.

(12:40:10) gp > plot(x=-10,10,2^x+7)

you can type "?10" at pari prompt (without quotes) for help on plotting functions. If you have the bitmaps associated with some application (like ms fax wiewer, ACDSee, whatever) then you can also use "ploth" function. That would make a nice bitmap/jpg/gif from your graphic and send it to the associated application, so you can see it on screen in a nice graphic mode.
Try:

ploth(x=-10,10,sin(x)/x)

is there any way for it to only use integer values ? I figured it out, in my older version of GP it does it right inside a new window of pari/gp

How about "ploth(X=0,2*Pi,[sin(X),cos(X)],1)" ?

Something that almost works

Code:

plot(x=-5,5,sqrt(25-x^2)); plot(x=-5,5,-sqrt(25-x^2))
