I need to plot a model of the amount of internet users starting from 1995 - 2024 in the US.


 

Example : Quadratic Modeling: Internet Users

 

"I:={[[-0.25 t^(2)+16.9 t-50,,5<=t<=24],[,]]"

``

"I  ="number of users of internet

t = time i.e 5 = 1995 year

I'm having problems with Multiplying Complex Numbers in Maple 2019.

Thanks in Advance.

Example 2: Multiplying Complex Numbers

 

(2-i)(4+3*i)

(3+2*i)(3-2*i)

4*i(-1+5*i)

(3+2*i)^2

2-i(4+3*i)

 

3+2*i(3-2*i)

 

4*i(-1+5*i)

 

(3+2*i)^2

(1.1)

I'm still trying to get used to the commands. How do you find the height of a cylinder and plot to a graph?

Thanks in Advance.
 

Example: Using a Formula

 

Height of a Cylinder:

ex6v := 600

ex6r := 4

ex6h := ex6v/Pi(ex6r)^2

600/Pi(4)^2

(1.1)

Is there a way to enter a formula into the coloums to generate the output?
I did the Table of Values by Hand which will take a long time for real data.

Thanks in Advance

Why are these functions not graphed correctly?

"ex17f5(x):=2 x^(3)-1:"

"ex17g5(x):=((x+1)/(2))^(1/(3)):"
