Thank you so much for the help so far Acer. I wanted to ask you, but how would I go about having the values put into different tables? I got the graphs down, but I am assuming that there may be a way to import the values and solve equations with the values in the data tables for each graph? That may have been confusing but here is what I mean:

So in one of the first programs I posted. I had the graphs which gave me data like so.... 

Basically what I am saying is that is there a way we can convert these values from data1 or data2 in tables and be able to solve absolute value and error?

Im sorry about that. This is my first time reaching out to get help. I will not do that again. I have updated my code to what you have stated with me putting a "*" to state that it is multiplication of two variables instead of variable "xy". As well as what you stated on how I should use y(x) instead of just y. One thing I wanted to ask but why is when the initial value when it is 0, the graph seems to be almost horizontal? Though when I have the initial value of y=1, then the graph seems to curve upwards? I think I must be putting the initial value incorrectly into the code. Also with data2, I am trying to display all three graphs together on the same graph to compare them? I think the code is correct as I see the red graph, blue graph, and black graph. I think just since the initial value condition is off that it is messing things up. Would those things be affected if I switched the step sizes and values with each other and had 0.05 (201) first and 0.1 (101) second?
