Hoe do you plot two vectors of data as a bar plot or historygram. I tried the statistics package but could not plot a bar plot that shows the proper relation of numbers in vector x to numbers in relation to vector y. Vector x contained years as data, and vector y contained for example crime data per year.

I have a formula, which is called the cube law. It requires input between 0 <= x <= 1. When creating  a procedure I run into all kinds of problems and get nothing but error codes. Trying to use assume works, it puts a tilde mark on the variable x, but doesn't restrict the input. Here is the formula the way it is writtin in a book on calculus:

f(x) := x^3/x^3+(1-x)^3 (0 <= x <= 1).

Trying to restrict the input to be restricted as required by the relational statement has been proven fruitless.

Any help would be greatly appreciated, thanks,

Rolf.

When I am plotting functions with known asymptotes, they do not show, even though the text books show them.Also, I can use the Student Calculus1 Asymptote function to calculate that there is an asymptote, but when plotting, they don't show up.I perused plot/options but cannot find an option that I could enable/disable to have the asymptotes show in the graphs.

Is it possible to include a step in the range when plotting a function? For example, plot(sin(x)-1/2,x=-1000..1000, in steps of 10) or similar syntax.

Your help would be greatly appreciated.

thanks, rolf.

How can I create a vector using a step index, for example, using the function output f:=1/i+1 and alternate it with a zero

 that produces a vector such as,  0,1/2,0,1/3,0,1/4,0,1/5.....?

Every attempt I tried failed.
